Ball Transfer Units and Tolerance Rings


Ball Transfer Units

Ball Transfer Units

Various designs with load capacities of up to 25,000 N. Ball Transfer Units make light work of shifting, turning and guiding unitized loads. Over the years their value as a conveying element in feed devices, machining and packaging equipment has become more and more evident.


  • Smooth running
  • Precise rotation and full load-carrying capacity in any installed position
  • Greater productivity at lower cost
  • Easy mounting and extraction
  • Conveying speed of up to 2 m/s in all types
  • Designs to suit all standard and many special applications

Tolerance Rings

Tolerance rings made of hard, embossed spring band steel are frictional-locking connection elements. Rexroth 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.
