Saint-Gobain Performance Plastics - Bearings and Tolerance Rings Crown Tolerance Rings RENCOL®

A RENCOL® crown ring can be a SV or HV style ring with fingers instead of waves. These fingers are designed to withstand large tolerances and absorb vibrations/movement. This type of ring is generally used for large radial clearances of less than or equal to 3mm.

The RENCOL® Tolerance Ring is a precision spring steel device, comprising a thin strip into which corrugations, or waves, are formed, each of which will act as a spring. This strip is then rolled into a ring.

Within the elastic limit of the waves that make up a tolerance ring, simple spring theory applies i.e. Force (N) -- F = K · c

We supply high volume international Original Equipment Manufacturers (OEMs) and Tier One suppliers with custom designed component solutions for use in a range of applications for customers in the most demanding industries, including Automotive, HVAC, Bicycle and Electronics.

We have decades in development and leading solutions with bearings and tolerance rings. Today, operating from 14 manufacturing bases and six R&D centres worldwide, we support our customers to develop even better systems using our components that deliver weight, space and cost savings, streamline assembly, reduce noise and extend the life of our customers' products.

RENCOL® HV ring with flanged end (a protruding rim that surrounds the circumference of the material) used for axial control or limiter, for example in steering column collapse mechanisms.

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.
