DIN 988 defines shim washers (adjusting washers) and support washers. They are thin, precise discs used to remove axial play between components and to back up retaining rings, without redesigning the shaft or the housing.
Shim washerPS series: compensates axial play in several thicknesses
Support washerSS series: backing for retaining rings

- Thickness. For shim washers, combine thicknesses to reach the required play.
- Function. Shim (PS) to compensate play; support (SS) to back up the retaining ring.
