4.1 Brief description
The CASM (⮑ Fig. 1) is a linear actuator designed to work in
factory automation. The drive is used exclusively for dy-
namic center compression or traction movement.
The linear unit (7) is powered through a coupling (5) by a mo-
tor (6). The motor (6), in direct drive, drives either a trapezoi-
dal or a ball screw system. Via the screw mount, the trape-
zoidal screw or ball screw system transforms the rotation of
the motor (6) into a linear motion of the actuator (8).
The rod leads and the other accessories transmit the actua-
tor power in the application.
