Linear Actuators

Power Your Innovations with VEVOR Linear Actuators


Linear actuators are essential devices that have revolutionized various industries by enabling precise linear motion and automation. Whether it's in manufacturing, robotics, healthcare, agriculture, or aerospace, the versatility and efficiency of linear actuators, including the renowned VEVOR brand, have made them essential components in countless applications. 


This article delves into the significance of linear actuators, highlights their different types and features, provides guidance on choosing the right product, and offers popular recommendations available on VEVOR.


Importance Of Linear Actuators


Linear actuators play a crucial role in various industries and applications of automation equipment. These devices, such as the 12V linear actuator or electric linear actuator, are widely used in manufacturing, robotics, healthcare, agriculture, aerospace, and many other fields. 


The importance of linear actuators lies in their ability to convert rotational motion into linear motion, offering precise control and positioning. Whether it's handling heavy duty loads, adjusting distance, or automating processes, linear actuators provide efficiency, accuracy, and convenience. In any situation that needs movement in a straight line, they are the solution.


Types And Features Of Linear Actuators


Linear actuators, including electric linear actuators, come in various types, each designed to meet specific requirements. Here are some commonly used actuator products and their features:


  • Electric Linear Actuators


These linear actuators use electricity to activate and offer precise control over linear motion. They are compact, reliable, and easy to integrate into existing systems. Electric linear actuators can be operated through switches, buttons, or programmable controllers, making them ideal for automation and robotics applications.


  • Hydraulic Linear Actuators


Hydraulic actuators use hydraulic fluid to generate linear motion. They provide high force capabilities, making them suitable for heavy duty applications. These actuator products are commonly used in industrial automation and automotive systems.


  • Pneumatic Linear Actuators


Pneumatic actuators use compressed air to create linear motion. They are known for their quick response time and high speed operation. Pneumatic linear actuators are widely used in industrial automation that requires fast and repetitive motion, such as packaging, assembly, and material handling.


Choosing The Right Linear Actuator


When selecting a linear actuator, there are several factors need to be considered:


Load Capacity


Determine the maximum weight the linear actuator will need to lift or move. Once you’ve done that, choose a linear actuator with a load capacity slightly higher than the actual requirement to ensure optimal performance. This is important since you will involve a high force in daily operations.


The measure for this factor is usually in “Newtons”. It is the standard unit of force. Whatever the type of linear actuator it is, the measurement stays the same. For usual situations, a thousand Newtons of pushing force can be enough. In case you don’t know, the ball screw that linear actuators utilize enabled them to deliver such high force without a problem. 


Speed and Stroke Length


You may encounter the terms “retracted” and “extended” length. That is your basis on how far can a linear actuator extend its cylindrical component in a straight line. Also, don’t forget to consider the desired speed of the extension and retraction. 


High speed may be often preferred but variability can be more important in certain situations. Moreover, do note that different applications may require different speeds and stroke lengths.


Power Source


Decide whether an electric linear actuator or other types of linear actuators are best suited for your application, be it manually or for automation equipment. While doing so, consider factors such as power availability, control requirements, and environmental conditions.


For electric linear actuators, the power source is usually 12V. The voltage rating is similar to those being used by appliances such as the TV.


Mounting Options


Check the available mounting options for the linear actuator and select a product that can be easily installed in your situation. Common mounting options include rear clevis, front clevis, trunnion, and foot mounts.


Environmental Considerations


Assess the operating environment for the linear actuator, including temperature, humidity, and potential exposure to dust, water, or chemicals. After assessing, choose accordingly a high quality linear actuator with appropriate protection ratings to ensure durability and reliability.


Special Functions and Maintenance


Linear actuators, including electric linear actuators, often come with special functions and features to enhance their performance and versatility. Some common special functions include:


  • Position Feedback


Linear actuators equipped with position feedback sensors provide accurate positioning control, allowing for precise and repeatable motion. Moreover, an actuator utilizing a stepper motor makes it easier to process the feedback. 


  • Limit Switches


Limit switches help prevent over-travel and provide end-of-stroke detection, ensuring safe operation and protecting the linear actuator from damage.


  • Control Options


Control options for linear actuators can be many. They can be manual switches, remote controls, or integrated options for automation equipment such as programmable logic controllers (PLCs) or microcontrollers. Speed controllers are also a good feature in order to vary the actuating speed. 


To ensure the longevity and optimal performance of your linear actuator, regular maintenance is essential. Keep the linear actuator clean and lubricate the ball screw as recommended by the manufacturer. 


Also, you can inspect it for any signs of wear or damage, including on parts that have implemented special functions such as stepper motors, limit switches, and speed controllers. Furthermore, follow the maintenance guidelines provided by the manufacturer to extend the lifespan of your linear actuator.
