The Precision Motion Drive System from Amacoil/Uhing is a Uhing Model RG rolling ring linear drive integrated with a motion controller for precision linear motion applications...

The Amacoil-Uhing Model RS drive nut provides smooth backlash-free linear motion in machine design. Unlike a screw, the RS drive nut runs on a smooth shaft without threads.

Changing linear pitch on Uhing rolling ring linear drives is now faster and easier using a lever control option on the drive unit.
