Washers FAG U202

The U202 steel washer from FAG Rolling Bearings, measuring 24 x 35 x 4 mm, provides a precisely fitting support surface for axial bearing arrangements.

The U202 shim is used in mechanical engineering and fixture construction as a precision component for rolling bearing assemblies. Manufactured from steel, the shim ensures even load distribution in the axial force path. This component from FAG Wälzlager has a bore of 24 mm, an outer diameter of 35 mm and a width of 4 mm. These standardised dimensions allow for precise alignment with adjacent shaft sections or housing components.

What functions does the U202 shim perform in the design?

This component creates a defined contact surface or spacing within a rolling bearing assembly. In assemblies with axial bearings, shims frequently act as a support surface, provided that the surrounding structure is not designed to act directly as a running surface. The washer absorbs axial forces and transmits them in a planar manner to the surrounding machine component. Thanks to its steel construction, the U202 shim washer can withstand mechanical surface pressures.

What are the key considerations regarding the dimensions of the U202 shim?

To ensure correct operation, users must check that the inner diameter of 24 mm and the outer diameter of 35 mm match the connecting dimensions before installation. The washer width of 4 mm determines the axial play in the overall system. A clean, burr-free fit against the end faces prevents tilting. Flat mounting plays a key role in preventing uneven loads in the shaft train.
