Z 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 as specified in DIN471 and DIN472,DIN983 and DIN 984 or lock washers as specified in DIN6799.shim rings may only be used where the contact faces are smooth. they shall not suffer any deformation when used with components that have rounded edges (shaft collars stepped holes)
supporting rings are intended for used with circlips or lock washers to ensure that do not deform when subjected to excessive axial forces as may be expected where the edges of machine components are rounded or chamfered.
