Tolerance Rings are highly engineered frictional fasteners used to economically join mating cylindrical parts. Manufactured from high quality spring steel or stainless steel strip, tolerance rings are widely accepted as a fastening device capable of handling torque transfer, axial retention and radial loading between mating machine parts.

Technical and economical advantages ensured by use of the Tolerance Rings include:

1. Rapid, low cost assembly 2. Wider dimensional tolerance of mating diameters for interference fits 3. Compensation of Thermal expansion between mating materials 4. Elimination of keys, pins, adhesives, D-Shafts, threads and splines 5. Compensates for small amounts of misalignment of up to 1/2º draft angle 6. infinite rotational indexing of parts prior to assembly 7. Re-workable
