An Introduction to Electric Linear Actuators


A linear actuator is different compared to an electric motor as it can convert rotational motion to linear motion. Most hydraulic actuators are subject to common problems such as worn seals, leaks, and pressure changes from the pump. An electric linear actuator can replace these problems providing a safe and clean device for your applications.


There are different variations in the basic design of linear actuators such as ball screw actuators, worm drive actuators, acme screw actuators, tubular linear actuators, and linear slide actuators.


As an experienced electric linear actuator manufacturer, we have developed in-house design and manufacturing processes of actuators.


How to Choose the Right Linear Actuator?


1)  Force


The weight of the object to be lifted or pushed will determine how much force your linear actuator requires. Usually, a small linear actuator is designed to handle small objects. On the other hand, a large one can handle heavy duty applications.


2)  Efficiency


A linear actuator must overcome friction, so you need to consider the amount of friction involved in your application. If your application demands high efficiency, you should select a high precision linear actuator. If not, a relatively less expensive actuator will suffice.


3)  Stroke Length


The stroke length is the stretchable distance of a linear actuator inside the equipment. It determines the retraction extent of the actuator.


4)  Power Supply


Based on the availability of the power supply, you need to choose either a DC linear actuator or an AC linear actuator. When it comes to DC linear motion actuators, 12V and 24V versions are the most commonplace.


5)  Speed


You need to know how much time the actuator should take to finish the task in a single stroke. In short, you need to combine the speed of your linear actuator with the amount of force generated by the motor. High-speed linear actuators have a speed of more than 40mm/s.


6)  Work Environment


To choose the right linear actuator, you need to consider various work environment factors such as temperature, IP degree, noise, and installation size. For example, if your application requires a noiseless operation, we can design a silent linear actuator. An IP66 actuator, on the other hand, is ideal for a waterproof work environment.
