How does a linear actuator work?

Release time:

2024-05-13


In most electric linear actuators, a motor turns a lead screw, which moves a threaded nut along the screw, causing the actuator rod to extend or retract. The direction of the motor’s rotation determines whether the rod moves in or out. Other types, like hydraulic or pneumatic actuators, rely on pressurized fluids or air to move a piston.
