Washers FAG U205

FAG’s u205 washers are made of steel and, with an outer diameter of 50 mm, provide a dimensionally stable bearing surface for roller bearing assemblies.

FAG’s u205 shims serve as spacers in mechanical assemblies and rolling bearing arrangements. Manufactured from steel, these shims absorb axial forces and distribute any resulting surface pressures evenly across the surrounding structure. With an outer diameter of 50 mm and a width of 5.5 mm, they facilitate the precise axial positioning of adjacent machine components. Industrial users employ this design in new constructions as well as for targeted repairs of worn-out units.

What are u205 shims suitable for in practice?

In industrial drives, gearboxes and bearing seats, u205 shims primarily fulfil two functions: tolerance compensation and load-distributing support. They prevent components from shifting axially under operational loads or bearing rings from pressing into softer mating materials at specific points. Technicians primarily use these steel washers where flat contact surfaces are required for rotating components or stationary bearing housings. The component helps to minimise wear on adjacent housing walls and maintain the precise fit of the entire bearing assembly.

What is important when it comes to the steel version of the u205?

When integrating u205 shims into existing designs, the dimensions and material properties are crucial. Steel offers high dimensional stability against static and dynamic compressive forces, enabling the shim to retain its flat, parallel shape even under continuous load. Design engineers and maintenance personnel adapt the installation space to the outer diameter of 50 mm and the thickness of 5.5 mm. Careful installation ensures that the contact surfaces bear the load across their entire area and that no harmful bending stresses arise at the bearing point.
