Washers FAG U203
The U203 washer from FAG Wälzlager, made of steel and measuring 26 × 38 × 4 mm, serves as an axial support surface in bearing assemblies.
The U203 shim acts as a specific stop or spacer in rolling bearing arrangements used in mechanical engineering and plant construction. This component from FAG Wälzlager positions parts between rotating and stationary elements. Made of steel, the washer absorbs axial compressive forces and distributes them evenly across the adjacent structure. This serves to protect the surrounding components from direct contact wear and friction damage.
In which assemblies is the U203 shim used?
Common applications include general fixture construction, gearboxes and industrial powertrains. The washer is used when axial clearances need to be adjusted or when component shoulders require a flat metallic contact surface. Thanks to its flat design with a width of 4 mm, the component is suitable for constructions where compact installation spaces offer little axial clearance for wide bearing rings.
What are the key considerations when selecting the U203 steel shim?
The structural connection dimensions are crucial to its function: the 26 mm bore determines the shaft fit, whilst the 38 mm outer diameter specifies the support within the housing. Steel withstands high surface pressures and counteracts the running-in of rotating mating parts. During assembly, clean, flat surfaces ensure a level fit, thereby preventing misalignment in the axial guidance of the rolling bearings.
What are the dimensions of the U203 washer?
The U203 washer has a bore of 26 mm, an outer diameter of 38 mm and a thickness of 4 mm. These dimensions ensure a precise fit on corresponding shafts and housing shoulders in industrial mechanical engineering applications.
What material is this component made of?
This component is made entirely of steel. The material retains its shape under load, absorbs mechanical compressive forces and protects adjacent machine parts from localised wear and deformation during operation.
What is the function of the washer in a bearing assembly?
A washer is used for axial positioning, to provide spacing, or as a defined contact surface for adjacent components. It ensures that axial forces are distributed evenly across its surface and protects housing materials from mechanical abrasion caused by adjacent bearing parts or shaft shoulders.
What should you bear in mind when fitting the windscreen?
Before fitting, the shaft and mounting bore must be thoroughly cleaned of dirt and swarf. The washer must sit flush against the stop shoulder. Avoid misalignment or applying excessive force when sliding it on, to prevent damage to the contact surfaces.
Can the U203 washer be used in combination with other roller bearings?
Yes, it can be flexibly combined with various types of rolling bearings, such as axial bearings, needle roller bearings or radial bearings, provided that the mounting dimensions of 26 mm (internal) and 38 mm (external) match the shaft and housing shoulders of the design.
