Washers FAG U222

The FAG U222 steel washer, measuring 135 × 165 × 14 mm, serves as a robust spacer and fitting component in demanding roller bearing assemblies.

The U222 shim is an accessory for FAG rolling bearings used in industrial assemblies. With an internal diameter of 135 mm, an external diameter of 165 mm and a width of 14 mm, the component functions as a dimensionally stable spacer or support washer. Manufactured from solid steel, the washer reliably absorbs axial compressive forces when installed. It supports the precise positioning of rotating machine elements and protects adjacent components from direct wear. Maintenance engineers and designers alike appreciate its dimensionally accurate design for stable assemblies.

What is the FAG U222 washer suitable for?

Maintenance engineers primarily use the U222 shim washer for axial fixation, to compensate for clearance or as a defined contact surface in rolling bearing assemblies. With an internal diameter of 135 mm, the washer fits onto appropriately sized shaft sections. It is used wherever adjacent structures need to be mechanically unloaded or structural clearances within the housing need to be precisely bridged.

Typical applications can be found in general mechanical engineering as well as in gearbox and bearing assemblies subject to axial loads. During repairs, the washer serves as a precisely fitting replacement to compensate for axial play and restore the correct alignment of bearing positions. Workshop managers can thus minimise downtime during scheduled overhauls.

What are the key dimensions of the U222 shim?

The key factors for selecting the U222 shim are the internal diameter of 135 mm, the external diameter of 165 mm and the shim width of 14 mm. Design engineers and purchasers must check whether the washer provides the necessary radial clearance relative to the shaft and lies flush against the bearing rings or housing shoulders.

The steel material withstands high mechanical compressive loads and prevents plastic deformation under axial load. During assembly, ensure that the contact surfaces are clean and free from burrs or dirt particles so that the component bears the load across its entire surface. For distributors and commercial buyers, FAG offers this part as a reliable standard component for recurring replacement requirements.
