Q: What is a Linear Actuator?
A: Put simply, an actuator is something that converts energy into motion. It can also be used to apply a force. An actuator typically is a mechanical device that takes energy, usually created by air, electricity, or liquid, and converts that into some kind of motion. That motion can be anything from blocking to clamping to ejecting. Actuators are typically used in manufacturing or industrial applications and may be used in things like motors, pumps, switches, and valves. Read More

Intro to Linear Actuators (PDF)
When students are trained in classic mechanical engineering, they are taught to construct a system using conventional mechanical components to convert rotary into linear motion. Converting rotary to linear motion can be accomplished by several mechanical means using a rotary motor, rack and pinion, belt and pulley, and other mechanical linkages, which require many components to couple and align. Although these methods can be effective, they each carry certain limitations. Conversely, stepper motor-based linear actuators address all these factors and have fewer issues associated with their use. The reason? Rotary-to-linear motion is accomplished in the motor itself, which translates to fewer components, high force output, and increased accuracy. Read More
Comparison of Linear Actuators with Pneumatics and Hydraulics (PDF)
When deciding whether to use hydraulic or electromechanical actuators in a particular application, the sole deciding factor is: which best meets the technical and economic demands of the application. Read More
