Linear Actuators

Micro-Drives' line of linear actuators are designed to be used in conjunction with Micro-Drives line of DC motors, Brushless DC motors, Precision Gearheads, and Encoders to provide reliable, repeatable linear actuation. The linear actuator's small package size allows for precise positioning in a small envelope.

These linear actuators are ideal for applications requiring a combination of precise positioning, rapid motion and long life. Typical applications include X-Y tables, medical equipment, photonics and optics devices, telecommunications equipment, valve control, and numerous other uses.

Custom linear actuator mechanisms are available. Please contact your Micro-Drives application engineer for assistance.
