What is a Linear Actuator and What Are They Used For?

In its most basic form, a linear actuator is used to move or position some object or device to a predetermined destination or position. The application may require a high level of precision (microns) or more coarse positioning.  ( +/-  ¼ inch) There are many different basic types of linear actuators and they all have advantages for specific applications:

  • Modified Acme

  • Ball Screw

  • Electric Solenoid

  • Stepper based

  • Servo Based

  • DC Motor

  • Voice Coil

  • Pneumatic

  • Hydraulic

  • Simple Mechanical linkage

Linear actuators have thousands and thousands of applications in the real world and are everywhere, but because they are usually hidden within a machine or mechanism, they are not readily noticed by the untrained eye.  Below is a very short list of typical applications:

  • Automated laboratory machines

  • Automated clinical chemistry processing

  • Dental equipment

  • Biomedical systems

  • Gene sequencing machines

  • Robotics

  • Packaging machines

  • Kiosk vending machines

  • Precision valve and flow control

  • Automated door locking mechanisms

  • Automated storage and retrieval systems

  • Integrated circuit manufacturing machines
