UHING rolling ring drives are friction drives which convert the constant rotary movement of a plain shaft into a traversing movement. They operate like nuts on a ball screw but have a pitch – either right-handed or left-handed – that can be precisely adjusted and can equal zero. This effect is achieved by using pivoted rolling rings that are mounted on roller bearings and have a specially shaped running surface which is pressed against the rotating shaft. A roller level capable of making contact with cams arranged along the stroke path makes it possible to implement even complicated patterns of motion.
UHING devices are commonly used for cable winding applications or where you need to run product evenly off a spool or onto a production platform.
