Washers FAG U306

The U306 washer from FAG Wälzlager, made from durable steel and measuring 45 x 62 x 7 mm, is designed for precise axial support.

The U306 shim acts as a mechanical compensation and functional element in rolling bearing applications. With an inside diameter of 45 mm, an outside diameter of 62 mm and a width of 7 mm, this steel washer creates a precisely defined contact surface between the housing, shaft or axial rolling elements. Companies use this component specifically when the adjacent connecting structure cannot be used directly as a running or support surface, or when axial distances need to be bridged with dimensional accuracy.

What is the U306 shim suitable for in industrial applications?

Design engineers and maintenance technicians primarily use this washer for defined force transmission in axially loaded assemblies. The U306 shim serves as a stable interface to distribute axial forces over a wide area and transfer them into the surrounding structure. Typical applications can be found in general mechanical engineering as well as in industrial bearings subject to axial loads, where the component functions as a spacer ring, thrust washer or support washer. The steel used withstands high surface pressures and helps to reduce wear on the surrounding components.

What is important when fitting the U306 washer?

For flawless operation, precise dimensional accuracy in the bearing seat is essential. Before installation, check the geometry of the mating dimensions: the 45 mm bore requires a suitable shaft guide, whilst the 62 mm outer diameter requires sufficient clearance within the housing. The overall height of 7 mm determines the axial play of the entire bearing assembly. Ensure that the contact surfaces are clean and flat, free from dirt particles, so that the washer sits flush without any play and tilting is prevented during operation.
