Shim rings

Shim rings are designed to prevent machine components from moving axially. The preferred application of these rings is to compensate for the play of such components where secured by circlips or lock washers. Supporting rings are intended for the use with circlips or lock washers to ensure that they do not deform when subjected to excessive axial forces as may be expected where the edges of machine components are rounded or chamfered.
