USA Tolerance Rings TR6205 Tolerance Ring, 205/304 Size, 2.0472" ID, 0.5906" Groove, MFR ID 85HFR60

Tolerance Rings can save your design when mounting ball bearings. These unique circular fasteners can secure and mount ball bearings within housings or to shafts by exerting radial holding forces. A series of equally spaced waves or corrugations formed into their circumference act as springs to retain ball bearings in place. - The amount of compression of these waves, the inherent properties of a particular tolerance ring configuration, and the properties of the mating surfaces determines the holding force strength.
