Support washers & shim rings

Technical drawing - Support washers

Support and shim washers are flat discs that are used where axial clearance needs to be compensated for. This could be on a mandrel where there is a safety ring/bearing, in between which there is a clearance that needs to be compensated for. By combining the different thicknesses of the washers, you can compensate for the clearance precisely. Support washers are the thickest for compensating for larger clearances, and shim washers come in thin thicknesses with differences in thickness of as low as 0.1mm, and tolerances of 0.03 to 0.05mm.

The stock number of a shim washer consists of one letter and five digits (S7****)

The stock number of a support washer consists of one letter and five digits (S7****)

Support washers over 1.5 mm thickness are ground on the surfaces.

Description

Support washers and shim rings are flat washers used in combination when axial clearance must be offset. This could be on a shaft where there is a locking ring/bearing, between which clearance must be offset. By combining washers of different thinckness, you can preciesly offset the clearance.

Support washers of over 1,5 mm thickness have ground surface.

Surface

Phosphatised and oiled.
