Washers SKF U220

The SKF U220 steel washer, measuring 125 × 155 × 14 mm, provides a precise bearing surface for axial bearing arrangements.

The U220 shim provides maintenance engineers and designers with a dimensionally accurate steel component. In rolling bearing arrangements, this component serves to absorb axial forces and transfer them to the surrounding structure. Where shaft or housing shoulders cannot serve directly as contact surfaces, this component provides the necessary transition. SKF’s manufacturing process meets industrial quality standards and facilitates the rapid procurement of spare parts during ongoing operations.

What is the U220 washer suitable for in mechanical engineering?

The washer is used in bearing arrangements subject to high axial loads, where axial forces need to be supported. It frequently functions, in combination with axial bearings, as a defined counter-surface on shafts or within bearing housings. As the contact surfaces of adjacent machine parts rarely have the required surface finish, the use of such a steel washer protects the surrounding area from direct wear. Thanks to its robust cross-section, the component is suitable for demanding industrial applications.

How important are the dimensions of the U220 for installation?

Before assembly, the geometry must be precisely aligned. With an internal diameter of 125 mm and an external diameter of 155 mm, the cross-section helps to distribute axial surface pressures evenly. The overall height of 14 mm plays a key role in determining the axial clearance of the entire assembly. Ensure a clean, burr-free contact with the flat surface to prevent any misalignment that could impair the service life of the adjacent rolling elements.
