Specification

RENCOL® SV style rings have a free-state diameter smaller than the shaft diameter over which they are to be installed, so that when mounted to the shaft, the rings conform to and become self-retaining on the shaft.  The ring sits on the shaft with waves on the outside to be compressed by the bore of the housing.

Engineered Fastening

The RENCOL® Tolerance Ring allows a simple consistent joint of cylindrical parts using dissimilar materials without the complications and cost of adhesive, secondary machining operations or machined details, such as splines or threads.  The Tolerance Ring sits between the two components resulting in an engineered fastening.

Torque Transfer

In a torque transfer application, the RENCOL® Tolerance Ring sits between the driving shaft and the gear/pulley.  The amount of torque is controlled by the design characteristics of the RENCOL® Tolerance Ring. The RENCOL® Tolerance Ring is an inexpensive solution which eliminates the need for costly machining operations such as keyways.
