Tolerance Rings Categories
Rings - Tolerance
Tolerance rings allow looser tolerances for assembly of parts such as bearings, pulleys and gears.
Allows looser tolerances of components. Ideal for mounting ball bearings. Useful for salvaging worn parts. Permits low cost assembly by eliminating the need for conventional fasteners. Use Torque Transfer figures for gears and pulleys. Non torque transfer figures are for bearing applications.
