Product Principle：
Smooth Shaft Traverse Unit are friction drives which convert the constant rotary movement of a plain shaft into a traversing movement. They operate like nuts on a screw rod 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 Uhing rolling rings that are mounted on roller bearings and have a specially shaped running surface which is pressed against the rotating shaft. A roller lever capable of making contact with cams arranged along the stroke path makes it possible to implement even complicated patters of motion.
rolling ring Linear drives are non-positive drives which convert the constant rotation of a plain round shaft into reciprocating motion. They operate like nuts on a threaded bar, however the pitch both left-hand and right-hand can be fine-tuned or set to zero. This effect is achieved by using ball bearing based Rolling Rings which are designed to tilt on the shaft, their specially crowned running surfaces being pressed against the shaft as it rotates.
