Product overview

5.1

Function

The axis converts the rotary motion of the mounted motor into a linear motion of
the slide. The torque of the motor is transmitted to the slide via the toothed belt
drive (TB). The linear movement of the slide is precisely guided by the guide. The
integrated cover strip prevents abraded particles from penetrating the immediate
vicinity of the drive. Sensors and displacement measuring system enable the
monitoring of end positions, reference position and intermediate position.
