Washers

Shim Rings

DIN 988 shim rings are precision-engineered thin washers designed for fine-tuning axial clearance and compensating for tolerance build-up in mechanical assemblies. Produced with tight thickness tolerances from steel, stainless steel, or brass, they can be stacked to achieve precise dimensional spacing without deforming under load. They are critical in bearing assemblies, gearboxes, and electric motors to eliminate axial play and ensure accurate component alignment.
