Washers FAG U213

The FAG U213 steel washer, measuring 82 × 105 × 9 mm, is used for axial positioning in rolling bearing assemblies.

The U213 washer is a cylindrical steel washer for use in rolling bearing applications. With a bore of 82 mm, an outer diameter of 105 mm and a width of 9 mm, this component is used for defined axial guidance or spacing on the shaft. FAG rolling bearings are designed to meet industrial requirements for dimensional accuracy and dimensional stability. The washer can be integrated into bearing assemblies to adjust axial play or to protect bearing seats from mechanical wear.

In which assemblies is the U213 washer used?

The U213 shim is used in mechanical engineering assemblies in which shafts with a diameter of 82 mm are mounted or guided. The washer acts as a spacer ring between components that abut axially or serves as an axial contact surface for bearing rings. It is primarily used in bearing arrangements that require defined force transmission in the axial direction.

What are the key considerations regarding the dimensions of the U213 spacer washer?

When selecting and fitting the U213 shim, the exact mating dimensions are of paramount importance. The inner diameter of 82 mm is based on the shaft, whilst the outer diameter of 105 mm must be matched to the radial installation space. The width of 9 mm determines the axial clearance of the assembly. As the washer is made of steel, it is designed to withstand mechanical surface pressures. Ensuring that the contact surfaces are clean before insertion helps to prevent the washer from becoming misaligned.
