Washers FAG U201

The U201 steel washer from FAG Wälzlager, measuring 20 × 30 × 3.5 mm, provides a precisely fitting support for axial bearing assemblies.

In mechanical engineering, the U201 washer serves as a flat bearing surface for axial rolling element rings or as a stable spacer. This component from FAG Wälzlager has an internal bore of 20 mm, an external diameter of 30 mm and a width of 3.5 mm. In mechanical assemblies, the steel washer distributes axial forces evenly across the surrounding housing or shaft. In this way, the component protects softer machine parts from mechanical running-in.

What is the U201 washer suitable for in mechanical engineering?

Maintenance engineers and designers primarily use this washer where adjacent components are not hardened or have not undergone precision machining. The washer provides a robust mating surface for axial rolling elements. Typical applications are found in assemblies subject to significant axial loads. Users also employ the component to compensate for axial bearing play and to position components precisely on the shaft.

What is important to consider regarding the dimensions of the U201 shim?

Before installation, check the shaft fit and the available installation space. With a bore of 20 mm, the washer fits exactly onto the corresponding shaft, whilst the outer diameter of 30 mm provides the necessary radial coverage. The material thickness of 3.5 mm determines the axial spacing within the system. As the washer is made from solid steel throughout, it absorbs axial compressive forces whilst maintaining its dimensional stability.
