Product overview

5.1

Function

The electric cylinder converts the rotary motion of the mounted motor into a linear
motion of the non­rotating piston rod. The lead screw converts the torque of the
motor into a feed force. The linear movement of the piston rod is precisely guided
by the guide in the bearing cap. Sensors enable the monitoring of end positions,
reference position and intermediate position.
