How does a Linear Actuator work?

Knowing the ins and outs of how a linear actuator works can help you make an educated decision when selecting the right one for your application. How do they work? What features do they have? What benefits will they add to your application? Find out more in our guide below to help you decide.

How does a Linear Actuator work?

Linear actuators work by moving an object or piece of equipment in a straight line, moving an object extremely accurately and repeatably if required. The primary reason for designing a linear actuator into a system is for the need to move a payload in a linear fashion rather than a rotary one. As most conventional electric motors are rotary, a linear actuator is used to convert rotary motion to linear motion.

The electric motor is generally connected to the linear actuator by a flexible coupling or a belt, enabling the motor to be mounted either axially or perpendicular to the linear actuator. A variety of motor sizes can be mounted to these actuators depending on requirements.

Linear actuators have incorporated linear bearings that support the moving payload, as well as rotary bearings that support either the lead screw, ball screw or belt pulleys. This then allows them to operate as ‘stand-alone’ devices, making them easy to mount into existing machines and eliminating the need to design/manufacture very costly custom parts. To increase the load capacity and stability of a linear actuator system, they can be paired up with the payload carried between them, such as in an XY gantry style stage. In this case, a shaft or belt is often used to keep the two actuators in sync with each other.

Features of Linear Actuators

Linear Actuators have the following features:

Industries and applications for Linear Actuators

Linear Actuators can be used in various applications that require a load to either be lifted, lowered, pushed, pulled, rotated or positioned. Linear Actuators are used in industries including:

Types of Linear Actuators

Picking the correct type of linear actuator for your motion application can help you achieve the best results. Lead Screw Actuators, Ball Screw Actuators and Belt Actuators are three types of linear actuators that can be used in various applications to produce motion.
