Tolerance Rings

Dr. TRETTER®-Tolerance Rings

Tolerance Rings are a low-cost solution for shaft-hub-connection for production in series. With this machine element an optimal transmission of high torques is possible. This connection can be disconnected and is force-locking. This offers technical and cost-saving advantages compared to applications with feather keys or press fits.

The spring qualities of Tolerance Ring does not deteriorate when operating at continuous temperatures of up to 250 °C. Tolerance Rings presents thus possibilities for the joining of different material combinations with different expansion coefficients (e.g. steel ball bearings or ceramic bearings in aluminium housing). 

Tolerance Rings offer important technical and economic advantages: 

  • high torque capabilities
  • low cost through rapid assembly
  • permit wider machine tolerances
  • provide high temperature resistance
  • eliminate problems of differential thermal expansion of mating parts
  • compensate for misalignement
  • offer resistance against corrosion by a number of chemical substances
