Linear actuators are easy to mount and operate, require no maintenance, don’t leak hydraulic fluid, are easy to incorporate into an automated process and once installed they will work reliably under the toughest conditions year after year.
The main actuating components of a linear actuator are:
When the motor is powered, it turns the gearing. The gearing
multiplies the torque and reduces speed of the motor. The gears turn a
screw. The nut on the screw is attached to the extension tube and is
moved in or out depending on the direction the screw is turned.
