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.
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.
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.
The U213 washer has an internal diameter of 82 mm, an external diameter of 105 mm and a total width of 9 mm. These dimensions define the fit on the shaft as well as the required radial clearance in the surrounding housing. Before installation, it is advisable to check that the actual dimensions match these nominal dimensions.
The disc is made of steel and is designed for industrial applications subject to mechanical stress. The material absorbs axial forces and retains its shape under surface pressure. This ensures that the set clearance dimension remains accurate within the assembly, even under load.
Washers create a defined axial distance between adjacent components or serve as a flat contact surface for rolling bearings. They help to ensure that bearing rings do not come into direct contact with housing edges or retaining elements. They also facilitate the precise adjustment of bearing clearance along the shaft axis.
Faces on the shaft and housing that are parallel and free from contamination are essential for a stress-free fit. Dirt particles and burrs should be removed before installation to ensure that the component makes full contact across its entire surface. If the component is fitted at an angle, this will cause misalignment in the shaft assembly and may affect adjacent roller bearings.
Whilst a retaining ring engages in a groove and secures components against axial movement by means of a positive fit, the washer serves as a flat spacer and intermediate element. It has no spring-like properties or retaining lugs, but distributes axial forces evenly across its entire annular end face.
As a passive spacer, the disc does not require its own lubrication supply. It is usually lubricated via the lubrication system of the adjacent roller bearings or by the existing lubricant. A lubricating film protects the steel surface from corrosion and makes subsequent dismantling easier.
