What is Solenoid Valve & How it Work (A Step-By-Step Guide)
Solenoid valves are remote-controlled gatekeepers for fluids. They use an electromagnet, called a solenoid, to manipulate a metal plunger. When electricity flows through the coil, it magnetizes it, attracting the plunger. This movement opens or closes internal passages in the valve body, controlling the flow of liquids or gases. With a spring pushing the plunger in the opposite direction, solenoid valves come in two types: normally open (spring keeps it open until activated) and normally closed (spring keeps it shut until activated). These versatile valves are used in everything from car engines to irrigation systems. What is a solenoid valve? A solenoid valve is a type of electromechanical device used to control the flow of fluids such as air, water, gas, steam, or other liquids. It consists of a coil of wire (solenoid) wound around a metal core, which generates a magnetic field when an electric current passes through it. This magnetic field causes a plunger or armature to move within the valve body, either opening or closing a passage for fluid flow. This guide provides comprehensive insight into solenoid valves, detailing their operational principles and offering clear guidelines for understanding their functionality. How does a solenoid valve work? A solenoid valve operates by utilizing an electromagnetic mechanism to regulate the flow of fluid through a passage. It comprises essential components such as a solenoid coil, plunger, valve body, ports, and a valve seat. When an electrical current passes through the solenoid coil, it generates a magnetic field that moves the plunger. This movement either opens or closes the valve, controlling the flow of fluid. Depending on its configuration (normally closed or normally open), the valve either allows fluid to flow or blocks it. How a solenoid valve actually works using its components. Let’s take a normally closed (NC) solenoid valve as an example: When there’s no electrical current, the coil isn’t energized. The spring takes charge, pushing the plunger down. This action forces the seal on the plunger to block the space in the valve body, essentially closing the gate and stopping any fluid flow. When electricity is applied to the coil, it becomes a mini magnet. This magnetic field pulls the plunger upwards against the spring’s force. As the plunger rises, it lifts the seal away from the orifice. This creates a clear pathway for the fluid to flow through the valve, opening the gate. Once the electrical signal ceases, the magnetic field disappears. The spring regains control, pushing the plunger back down. This closes the seal on the space once again, stopping the flow of fluid. By using electricity to control fluid flow electronically, it offers a simple and efficient solution for various applications. Their compact size, reliability, and versatility make them a valuable component in modern technology. The Working Principles Of Solenoid Valve Solenoid valves have two main parts, the solenoid and the valve itself. The valve has openings, while the solenoid contains a coil, sleeve assembly, and plunger. When you send electricity through the coil, it creates a magnetic field. This field moves the plunger up or down, which opens or closes the valve’s openings. This action controls the flow of gas or liquid, like turning a faucet on or off. Advantages & Disadvantages Of Solenoid Valve Solenoid valves are great because they serve multiple purposes in many industries. They’re good for handling liquids or gases, and they are quite efficient because they don’t need a lot of wiring or money to set up. Advantages Disadvantages What Types of Valves Are Used in Solenoid? There are 3 types of valves that offer versatility and flexibility in various applications, allowing for precise control of fluid flow in different systems. Two-way Solenoid Two-way solenoid valves are commonly used for on/off control. These valves have two ports. One port is for allowing the fluid to flow in one direction when the valve is energized, and another port is for blocking flow when de-energized. Three-way Solenoid Valve Two-way solenoid valves are commonly used for on/off control. These valves have two ports. One port is for allowing the fluid to flow in one direction when the valve is energized, and another port is for blocking flow when de-energized. Three-way Solenoid Valve Four-way solenoid valves are a type of solenoid valve with four ports: two inlet ports and two outlet ports. They are commonly used in pneumatic and hydraulic systems to control the flow of pressurized air or fluid and to switch between different circuits or actuate double-acting cylinders. Different Types Of Solenoid Valve There are 3 types of Solenoid Valves Normally closed Solenoid Valve A Normally Closed (NC) Solenoid Valve is a type of valve that remains closed in its default state, without any electrical power applied to the solenoid. When an electrical current is applied to the solenoid, it generates a magnetic field that lifts the valve’s plunger, allowing fluid to flow through the valve. Once the electrical current is removed, the solenoid de-energizes, and the valve returns to its closed position, stopping the flow of fluid. Normally open Solenoid Valve A Normally Open (NO) Solenoid Valve is a type of valve that remains open in its default state, without any electrical power applied to the solenoid. When an electrical current is applied to the solenoid, it generates a magnetic field that pulls the valve’s plunger, closing the valve and stopping the flow of fluid. Once the electrical current is removed, the solenoid de-energizes, and the valve returns to its open position, allowing fluid to flow again. Bi-stable Solenoid Valve A bi-stable A solenoid valve is a type of Solenoid Valve that has two stable states or positions, hence the term “bi-stable.” Unlike traditional solenoid valves that require continuous power to maintain either an open or closed position, bi-stable solenoid valves only require a brief pulse of electrical current to switch between their two stable states. Once switched, they maintain their position without the need for continuous power. Direct, Indirect & Semi-Direct Acting Solenoid valves Direct Acting Solenoid Valves directly control the
How to Speed Up Linear Actuator: Step-By-Step Guide
If you’re wondering how to make a linear actuator faster, there are several proven ways to speed up your fast linear actuator safely. You can raise the voltage with proper control, change the gear ratio, get a higher lead screw pitch, or use a motor controller to fine-tune speed. Techniques like PWM control using an Arduino and switching to a high speed actuators type, such as hydraulic or pneumatic, can also help. Regular maintenance, reducing friction, and optimizing the mechanical load can further improve the performance of your fast actuators linear. What is fast linear actuator? A high speed linear actuator 12v is like a super-fast mover in a straight line. Designed to zip back and forth quickly, faster than standard units, these actuators use powerful motors and lightweight materials to move fast while still being accurate and reliable. Fast linear actuators are ideal for applications like robotics and automated machinery where speed and precision are essential. Effective Ways to Speed Up These Device To speed up linear actuator, you can adjust several factors. Increase the voltage to the motor for more power, modify the gear ratio to increase speed, and consider upgrading to a stronger motor. Reducing friction by lubricating moving parts and simplifying the actuator’s design can also help. Characteristics of High-Speed Linear Actuator High-speed linear actuators exemplify swift, precise motion with rapid acceleration and deceleration rates. Compact and lightweight, they boast efficient energy usage, integrating feedback systems for enhanced control. Their durable construction, low inertia, and versatile applications make them ideal for dynamic industrial settings, ensuring reliability, longevity, and ease of integration into diverse automation systems. 7 Ways to Speed Up Linear Actuator Here are 7 proven strategies to make your fast linear actuator operate at optimal speed: 1. Adjusting Voltage Increasing the voltage in a linear actuator can be a dangerous and potentially damaging process if done incorrectly. Before attempting any adjustments, it’s crucial to understand the specific model of your actuator and its capabilities. Improper voltage can lead to overheating, malfunctions, and even electrical shock. Here are some safe and recommended ways to increase the speed of a linear actuator: Pulse Width Modulation (PWM): Many linear actuators use PWM for speed control. Increasing the duty cycle (on-time) of the PWM signal can provide more power and speed within the actuator’s safe operating range. Control signal adjustment: Some linear actuators accept analog or digital control signals. Adjusting the signal within the specified range can increase the speed. Consult the manufacturer’s instructions: The manual or data sheet for your specific actuator should provide detailed information on its voltage range, safe operating limits, and recommended control methods. Never exceed the manufacturer’s recommended voltage for your specific model. Consider alternative solutions: Using a larger or more powerful actuator model may be a safer option than exceeding the voltage limits of your existing one. Gearing can be used to increase the force output of an existing actuator at the cost of reduced speed. Additional Considerations: Wear appropriate personal protective equipment and follow the manufacturer’s safety guidelines. Use specialized tools and techniques if required for precise gear adjustments. If you’re unsure about the process, consult with a qualified technician or contact the manufacturer for assistance. 2. Adjust Gear Ratio While adjusting the gear ratio within a single linear actuator is typically not feasible, here are the common approaches to achieve the desired speed-to-force characteristics for your application: Select the Right Actuator at the Outset: Manufacturers often offer linear actuators with varying gear ratios, each designed to provide specific speed and force combinations. Carefully review the available options to choose the model that best aligns with your project’s requirements. Utilize External Gearing: If necessary, you can install additional external gears to create a custom gear ratio that suits your needs. This approach involves adding gears between the actuator’s output shaft and the driven load. Employ a Motor Controller: For fine-tuning speed control without altering the gear ratio, consider using a motor controller or a linear actuator control board. These devices allow you to adjust the actuator’s speed, end limits, and sensitivity through electronic means. Additional Considerations: Ensure your application can handle the reduced force output before adjusting the gear ratio. Always consult the actuator’s user manual or contact the manufacturer for specific instructions and recommendations regarding gear ratio adjustments or modifications. 3. Lead Screw Pitch The lead screw is a crucial component that converts rotary motion into linear motion. Opting for a lead screw with a higher pitch (distance traveled per screw revolution) results in faster linear movement. Here are key approaches to achieving the desired linear motion speed with a lead screw pitch: Select the Appropriate Actuator: Manufacturers offer linear actuators with varying lead screw pitches. Each influences speed and travel distance per motor revolution. Choose an actuator with a pitch that aligns with your speed and distance requirements. Utilize External Gearing: Employ external gears to modify the effective lead screw pitch. Install a gear train between the actuator’s motor and lead screw to alter the rotational speed and linear travel distance per motor revolution. Control Speed Electronically: For fine-tuning speed without altering the lead screw pitch, use a motor controller or linear actuator control board. These devices adjust motor speed, end limits, and sensitivity, impacting linear motion without physically adjusting the lead screw. Additional Considerations: Lead screw pitch impacts speed and resolution. A finer pitch yields slower speed but higher resolution (smaller incremental movements), while a coarser pitch offers faster speed but lower resolution. 4. Use Motor Controller or LAC Board These devices offer fine-grained control over motor speed, allowing for precise adjustments. Check compatibility with your actuator model before purchasing a controller or board: Compatibility Check: Verify that the controller is compatible with your actuator model and voltage requirements. Consult the controller’s specifications and the actuator’s manual for confirmation. Electrical Connections: Connect the power supply to the controller, ensuring proper voltage and polarity. The linear actuator’s motor wires to the corresponding terminals on the controller. If using external control signals (e.g., switches, sensors), wire them to the appropriate controller inputs. Configuration (if applicable): Some controllers may require programming or
What is a Rotary Actuator and How Does it Work?
Rotary actuators are powered by electricity, fluid pressure, or even manually. They are used in a variety of applications, including valve operation, mobile hydraulic equipment, aircraft, and motion control systems. In a fluid power system, rotary actuators act as output devices, delivering an oscillating motion within a limited range. They generate work through the application of fluid pressure against internal vanes. The choice of rotary actuator depends on the specific application requirements, such as speed, torque, and load capacity. What is a Rotary Actuator? Rotary actuators are a type of mechanical device that uses hydraulics to convert energy into linear motion. They are commonly used in heavy equipment, such as bulldozers, which use them to lift and move heavy objects. Rotary actuators are also used in closed-loop control systems, where they provide high-speed and high-force operation. How Does a Rotary Actuator Work? Fluid Power in Motion Within a fluid power system, rotary actuators function as output devices, delivering an oscillating motion within a limited range (think one full revolution). Right-rotary actuators generate work through direct fluid pressure against internal vanes, utilizing energy over distance. Imagine them as providers of rotating or angular movement – strokes within defined angles – generating a special kind of rotational work called torque. Circuitry Simplified Take a simple rotary actuator circuit diagram, where applied force translates to torque. When these actuators operate at low speeds with high torque, output torque becomes the key parameter for identification and rating. For choosing the right one, speed often takes a backseat to specific application needs. Torque Talk Measuring torque typically involves foot-pounds. For example, a two-foot-radius rotary actuator lifting a 200-pound weight would require 400 lb•ft of torque to do the job. Understanding this system-to-output torque relationship empowers designers to select the perfect actuator for each unique application. Types of Rotary Actuators Manual Rotary Actuator Often using worm drives for amplified torque in manual valve closure, these actuators are common on ball valves and quarter-turn butterflies. Their self-locking capabilities and large hand wheels make them worker-friendly. In the valve industry, they’re sometimes called manual overrides or gear operators. Electric Rotary Actuator Driven by electromagnetic power, electric rotary actuators rotate components. They offer indexing and control capabilities, allowing for multiple position stops with strokes. Their rotating element can be a circular shaft or a table, with shafts often featuring keyways and tables offering bolt patterns for mounting additional components. Specifications include voltage supply, maximum torque, repeatability, load capacity, operating temperature, rotation angle, and linear stroke. These actuators find diverse applications, from high-power switching gears to the automotive industry and packaging. Fluid-Powered Rotary Actuators Also known as pneumatic or hydraulic rotary actuators, these utilize fluid power delivered to cylinders to shift scotch yokes and rack-and-pinion assemblies or to rotors for straight shaft actuation. They typically move between 90° and 360° stops, based on the specific component or valve’s rotation requirements. Rack and Pinion Rotary Actuators These mechanical devices primarily control dampers or valves in industrial settings. The rack & pinion, a couple of gears, converts linear motion to rotational. A linear gear bar (the rack) connects teeth on a round gear (the pinion). When linear force is applied to the rack, the pinion rotates. Scotch Yoke Rotary Actuators This actuator features a sliding bar connected to a valve at one end and a yoke at the other, which includes a slot for a block that slides back and forth. The block is connected to a piston, so when the piston moves, the block drives the yoke, turning it and moving the bar to open the valve. Applications include oil and gas (valve activation for flow separation), mining (valve activation for separating nozzles), and water and wastewater (valve activation for separating feed lines, tanks, and filters). Helical Actuators Using a set of helical gears and a cylinder, this actuator converts linear input to an oscillating, rotary output. The cylinder contains three rotating pins and three helical slots machined within the outermost tube, which also features three keys to prevent excessive movement. When the cylinder moves, air force pushes down on the outermost cylinder for valve opening and squeezes a spring. When the air force is released, the spring pushes the valve to close again. Vane Rotary Actuator These combine the muscle of pressurized hydraulic fluid with the control of an electric motor. The electrical energy powers the motor, which controls a hydraulic pump that supplies the pressurized fluid for operating the valve. This self-contained system eliminates the need for a separate hydraulic power unit, simplifying design and enhancing reliability and safety. Vane Variety Pneumatic and hydraulic vane actuators use one or two vanes connected to a hub in a circular chamber or wedge shape, allowing vane rotation from 90 to 280 degrees. In these actuators, the hub simply rotates between stops using oil or air force to generate motion at the output stem. A double-vane actuator includes two opposite vanes for more torque but limited rotation compared to a single-vane actuator within a full circular chamber. Vane actuators are space-efficient and often used for transferring, clamping, or placing light loads in medium-speed applications. Pros and Cons of Rotary Actuators Rotary actuators, despite their versatility, come with their own set of advantages and disadvantages. Here’s a breakdown to help you decide if they’re the right fit for your application: 1. Advantages Durable and Powerful Rotary actuators boast exceptional durability and deliver relatively high torque for their size, minimizing maintenance needs. Angular Agility Their rotational capabilities allow them to move objects smoothly through any desired angle, offering greater flexibility compared to linear actuators. Stable Performance Once activated, rotary actuators maintain excellent stability even at low speeds, ensuring consistent operation. Smooth Motion They provide smooth acceleration and deceleration, making them ideal for applications that require precise control of movement. Easy Adjustments Rotary actuators equipped with stepping motors allow for simple adjustments in speed and position, enhancing their adaptability. 2. Disadvantages Torque Limitations Vane actuators, a common type, have limited torque and rotation compared to

How To Calculate Linear Actuator Position?
To precisely control a linear actuator‘s movement, calculating its position is key. This involves three crucial pieces of information: the actuator’s total travel distance (length), its starting point, and the desired final position. With these values in hand, a simple formula unlocks the secret: Position = (Final Position – Starting Position) / Length of Actuator. In essence, calculating the position clarifies the exact distance the actuator needs to travel to reach its designated endpoint. Mastering this calculation empowers you to program precise movements, ensuring your project operates with optimal efficiency and achieves flawless results. Demystifying Linear Actuator Position Calculations In the realm of industrial automation, linear actuators play a pivotal role in transforming rotary motion into linear motion, powering a wide range of applications from simple opening and closing mechanisms to complex robotic systems. Understanding how to calculate linear actuator position is crucial for ensuring precise control and achieving desired outcomes in these applications. The Basics Before diving into the calculations, let’s establish the fundamental concepts that underpin linear actuator position determination. The position of a linear actuator refers to the distance its rod or shaft has extended from its fully retracted position. This distance is typically measured in millimeters (mm) or inches (in). Dimensions The dimensions, displayed on the left side of the calculator, represent the information you input to specify your particular application. You can modify these values to determine a suitable linear actuator with appropriate mounting positions. Box Width The box width, measured in inches, indicates the width of the space underneath your hatch. This value may influence the physical size of a suitable linear actuator depending on the mounting positions. Typically, it corresponds to the width of the lid itself, but in some cases, you may have more space beneath the lid than its width. Box Height The box height, measured in inches, represents the depth of the space underneath your hatch. This value is particularly crucial when space beneath the hatch is limited, such as with a tonneau cover on a pickup truck, as it will restrict the physical size of a suitable linear actuator. When there is ample space underneath the lid, like with a trapdoor to a cellar, the box height becomes less significant. Lid Weight The lid weight, measured in pounds, represents the weight of the lid you intend to open or the size of the load you plan to rotate. Naturally, this value will significantly impact the selection of an appropriate linear actuator for your application. Max Angle The max angle, ranging from 0 degrees (closed) to 90 degrees, indicates the maximum angle at which your lid will open. Once again, this value will have a substantial influence on the potential linear actuators available for your application. Lid Mount Position The lid mount position, measured in inches, represents the location where your linear actuator will be attached to the lid. This value can vary from 0 inches to the box width or the end of the hatch. If you have flexibility in mounting the linear actuator to the lid, you can adjust this value to find results that best suit your application. However, in certain applications, the position where you can mount the linear actuator to the lid may be restricted. Actuator Type The actuator type refers to the type of actuator you intend to use. Your choice of actuator type may depend on your application or desired features, such as feedback options. You can explore the various types of linear actuators available in our store to determine which one is best for you. If you’re not particular about the type, you can experiment with different actuator types in the calculator to identify the one that best meets your needs. Choose Actuator Once you select a specific actuator type, you will then choose an actuator of that type with a particular stroke length. Since you may be unsure of the required stroke length, you can easily try out different lengths to determine if that particular actuator will fit your needs. Number of Actuators The number of actuators indicates the quantity of actuators involved in your application. While you can select either 1 or 2, the calculator will default to recommending using 2 actuators (one mounted on either side of the hatch) as it provides greater stability. It is never advisable to push a hatch open from just one side. We do offer the option to change to 1, but only do this if you are mounting the actuator in the center of the hatch. Factors Influencing Linear Actuator Position Several factors influence the position of a linear actuator, including: Calculating Linear Actuator Position Now that we’ve grasped the fundamental concepts, let’s delve into the practical aspect of calculating linear actuator position. The primary formula for calculating linear actuator position is: Position = Stroke × Extension Percentage Where: Example Calculation: Consider a linear actuator with a stroke of 100 mm and an extension percentage of 50%. Applying the formula, we get: Position = 100 mm × 0.5 = 50 mm Therefore, the actuator’s rod or shaft has extended 50 mm from its fully retracted position. Real-World Applications: Bringing Calculations to Life Linear actuator position calculations play a crucial role in various real-world applications, such as: Unveiling the Power of Precision Understanding how to calculate linear actuator position empowers engineers and technicians to make informed decisions regarding the selection, control, and optimization of these versatile components. By mastering these calculations, you can harness the power of linear actuators to achieve precise positioning, enhance automation processes, and optimize motion control systems. Embark on this journey of precision and unlock the full potential of linear actuators in your industrial endeavors! To get a full picture on how to install a linear actuator, read this blog.

Types of Linear Actuators There are many different types of linear actuators, each with its own advantages and disadvantages. The most common type of linear actuator is the electric linear actuator, which uses an electric motor to drive the screw or lead screw. Electric Linear Actuators Electric linear actuators use an electric motor to drive the screw or lead screw. Electric linear actuators are the most common type of linear actuator, and they are available in a wide range of sizes and configurations. Pneumatic Linear Actuators Pneumatic linear actuators use compressed air to drive the piston or rod. Pneumatic linear actuators are typically used for high-force applications, and they are often used in industrial settings. Hydraulic Linear Actuators Hydraulic linear actuators use pressurized fluid to drive the piston or rod. Hydraulic linear actuators are typically used for high-precision applications, and they are often used in medical devices and aerospace applications. Mechanical Linear Actuators Mechanical linear actuators use a mechanical mechanism, such as a screw, lead screw, or cam, to convert rotational motion into linear motion. Mechanical linear actuators are typically simple and inexpensive, but they may not offer the same level of precision or speed as other types of linear actuators. Piezoelectric Actuators Piezoelectric actuators use the piezoelectric effect to convert electrical energy into linear motion. Piezoelectric actuators are very precise and fast, but they are also relatively expensive and can only generate relatively small forces. Coiled Actuators Coiled actuators use a coiled spring to generate linear motion. Coiled actuators are compact and lightweight, and they can generate high forces, but they can be relatively noisy and have a limited stroke length. Electro-Mechanical Linear Actuators Electro-mechanical linear actuators combine mechanical and electrical components to convert rotational motion into linear motion. Electro-mechanical linear actuators offer a good balance of precision, speed, force, and affordability. Telescoping Linear Actuators Telescoping linear actuators use a series of nested tubes to extend their stroke length. Telescoping linear actuators are ideal for applications where a long stroke length is required, but they can be relatively bulky and expensive. Ball Slide A ball slide is a linear actuator that uses a series of ball bearings to achieve smooth and precise linear motion. Ball slides are often used in applications where high precision and repeatability are required, such as in medical devices and semiconductor manufacturing. Other Types of Linear Actuators In addition to the types of linear actuators described above, there are other types of linear actuators available – including Rotary Linear Actuators, Linear Slide Actuators, Linear Rod Actuators, Linear Piston Actuators, and Linear Motor Actuators. Components of a Linear Actuator Linear actuators are made up of a number of different components, including – Motor The motor provides the rotational force that is converted into linear motion. Electric linear actuators use an electric motor, while pneumatic linear actuators use compressed air, and hydraulic linear actuators use pressurized hydraulic fluid. Screw or Lead Screw The screw or lead screw is the threaded rod that converts rotational motion into linear motion. It is important to choose a screw or lead screw with the appropriate pitch and thread form for your application. Nut The nut travels along the screw or lead screw to convert rotational motion into linear motion. It is important to choose a nut that is made of a durable material and that is the correct size for
How To Install A Linear Actuator
A linear actuator is a device that converts electrical energy into mechanical motion. It consists of a motor, a lead screw, and a nut. The motor turns the lead screw, which in turn moves the nut along the length of the actuator. How Does a Linear Actuator Work? The motor in a linear actuator is typically a DC motor. DC motors are very efficient and can provide a high torque output. This makes them ideal for applications that require a lot of force, such as lifting and positioning heavy objects. The lead screw in a linear actuator is a threaded rod. The nut in the actuator is threaded to match the lead screw. When the motor turns the lead screw, the nut moves along the length of the actuator. This causes the load that is attached to the nut to move as well. Different Types of Linear Actuators There are two main types of linear actuators: electric linear actuators and pneumatic linear actuators. Electric linear actuators are the most common type of linear actuator. They are powered by electricity and are relatively easy to install and operate. Pneumatic linear actuators are powered by compressed air. They are more powerful than electric linear actuators, but they are also more complex and expensive. Choosing The Right Mounting Method for Your Linear Actuator The best way to choose the right mounting method for your linear actuator is to consider the specific needs of your application. Factors to consider include the actuator’s load capacity, stroke length, and range of motion. You should also consider the environment in which the actuator will be operating, as well as the budget and resources available to you. Clevis Mounting Clevis mounting is the most common mounting method for linear actuators. This method allows the actuator to pivot on both sides, which is useful for applications where the actuator needs to be able to move freely. Clevis mounting is also relatively simple and inexpensive to implement. Stationary Mounting Stationary mounting is another common mounting method for linear actuators. This method fixes the actuator in place, which is useful for applications where the actuator needs to provide a precise and stable force. Stationary mounting is also relatively simple to implement, but it does not allow the actuator to pivot. Trunnion Mounting Trunnion mounting is a less common mounting method for linear actuators. This method allows the actuator to rotate about a fixed point, which is useful for applications where the actuator needs to move in a circular or elliptical path. Trunnion mounting is more complex and expensive to implement than clevis or stationary mounting, but it offers greater flexibility in terms of actuator movement. Flange mounting This method uses flanges to attach the actuator to a mounting surface. Flange mounting is strong and durable, but it can be more complex and expensive to implement than other mounting methods. Foot mounting This method uses feet to attach the actuator to a mounting surface. Foot mounting is simple and inexpensive to implement, but it is not as strong or durable as flange mounting. Rod-end mounting This method uses rod ends to attach the actuator to a mounting surface. Rod end mounting is simple and inexpensive to implement, and it allows the actuator to pivot on both sides. Direct mounting This method involves directly attaching the actuator to a mounting surface without using any mounting brackets. Direct mounting is strong and durable, but it can be more difficult to implement than other mounting methods. How to Choose the Right Linear Actuator When choosing a linear actuator for your application, there are a few key factors to consider. Stroke length: The stroke length is the distance that the actuator can travel. Choose an actuator with a stroke length that is slightly greater than the distance that your load needs to travel. Force rating: The force rating is the maximum amount of force that the actuator can exert. Choose an actuator with a force rating that is greater than the weight of your load. Speed: The speed is the rate at which the actuator can move. Choose an actuator with a speed that is appropriate for your application. Duty cycle: The duty cycle is the percentage of time that the actuator can be operated at its full force rating. Choose an actuator with a duty cycle that is greater than the amount of time that you will be using it at full force.
