Ball Transfer Units / Tolerance Rings

Ball transfer units allow unit loads to be pushed, turned and steered with ease. They have been fully tried and tested as key modules of conveyor and feed systems, machining units and packing lines.
Tolerance rings made of hard, embossed spring band steel are frictional-locking connection elements. Tolerance rings allow components to be connected quickly and cost-effectively. They replace elaborate positive-locking feather-key, pin, spline or screw-in connections, and help avoid expensive machining work.
