What is a linear actuator？

Over the years, we have been focusing on the in-depth research and development of automation technology, professional design and manufacture of precision linear guide system, electric cylinder and non-standard automation machine, we have very rich experience.

From your user needs, conceive and plan the product, set the schedule, arrange the project implementation plan, based on a consistent understanding of the product concept and planning, make the product requirements more reliable and accurate. Conduct in-depth discussion, market research and communication on project design direction, design content, design style, etc., propose innovative ideas, determine the internal structure, parts material, surface shape, structural strength, mold optimization, etc.

Our products are widely used in the biotechnology, automotive, healthcare and pharmaceutical industries. In the spirit of "quality first, service first", we support our products and services all over the world, enjoy a high reputation.

There are various types of linear actuators, which can be divided into mechanical, hydraulic, pneumatic, piezoelectric, motor, linear motor, and telescopic types according to different driving methods and structural principles.

The working principle of a linear actuator varies according to different types, but it is generally achieved by converting the rotational motion of the motor into linear motion through a certain mechanism. For example, a screw type linear actuator drives the screw shaft to move in a straight line by rotating a nut; The gear and shaft type linear actuator drives a shaft to move in a straight line through gears and chains or belts; Linear motor type linear actuator uses electromagnetic fields to drive a coil to move in a straight line, etc.
