Washers FAG U313
The u313 washers from FAG Wälzlager, made of steel with an outer diameter of 120 mm and a width of 12.5 mm, are used to ensure precise axial alignment in bearing assemblies.
FAG Wälzlager u313 shims are used as mechanical spacer and compensating elements in industrial bearing assemblies. The solid steel construction is designed to precisely adjust axial clearances and to support bearing components against housing edges or shaft shoulders. Design engineers use these washers to adjust axial clearance or to create defined contact surfaces for adjacent rolling bearings. Thanks to their dimensionally stable construction, the components transfer axial operating forces directly to the surrounding structure.
What are u313 shims suitable for in mechanical engineering?
U313 shims are particularly suitable for assemblies that require axial preload or precise installation dimensions. Typical applications include bearing arrangements subject to high axial compressive stresses and with defined spacing requirements. The washer provides a smooth transition between the rolling element guides and the housing walls. The steel element absorbs axial surface pressures and reduces the direct running-in of bearing rings into softer surrounding components.
What is important regarding the 12.5 mm washer thickness?
With a width of 12.5 mm and an outer diameter of 120 mm, this washer offers high dimensional stability under axial load. When designing the assembly, ensure that the adjacent components rest flat against the end face. Otherwise, misalignment will lead to localised peak loads. For maintenance engineers and fitters, the fixed dimension facilitates quick replacement during maintenance work, as there is no need to assemble thin lamellae stacks.
What makes the u313 washers stand out?
These components from FAG Rolling Bearings are made of solid steel and have an outer diameter of 120 mm and a width of 12.5 mm. They are used in rolling bearing applications as pressure-resistant spacer or shim washers. Their main function is to distribute axial forces over a wide area and to maintain the exact distance between the bearing and the housing.
What is the function of washers in a rolling bearing?
Shims are used to mechanically adjust the axial bearing clearance and to create defined contact surfaces. They prevent axial rolling forces from acting directly on soft housing components and causing deformation there. Furthermore, fixed washer widths enable the reproducible alignment of shafts and gear wheels during assembly or repair.
What properties does steel offer in this component?
Made from steel, the disc offers high resistance to mechanical compressive stresses during operation. The material resists plastic deformation even under heavy continuous loads. Furthermore, steel is thermally and elastically compatible with standard bearing rings and machine housings, which helps ensure consistent behaviour of the entire assembly during temperature changes.
How does the 120 mm external diameter affect installation?
The external diameter of 120 mm determines the space required in the housing seat or at the mounting shoulder. To ensure correct operation, the housing bore must accommodate this diameter with a precise fit, without any tilting. Contact surfaces on the housing edge that are parallel to the plane help to ensure that axial forces are transmitted evenly around the circumference of the disc.
When is a solid pane 12.5 mm thick recommended?
A solid disc width of 12.5 mm is suitable for bearing locations with larger structural clearances or high mechanical loads. Compared with several stacked thin sheets, a single-piece washer prevents settlement under load. This simplifies installation during servicing and helps maintain a constant axial preload during operation.
What should be borne in mind when fitting the u313 washers?
Before installation, the flat surfaces of the disc and the contact surfaces of the shaft and housing must be thoroughly cleaned of dirt and particles. The disc must sit flat to prevent bending stresses. Lightly wetting the bearing seat with lubricant facilitates fitting and protects the contact surfaces from fretting corrosion.
