Washers SKF U309
SKF’s u309 steel washers, with an outer diameter of 90 mm and a width of 10 mm, provide a stable axial bearing surface for rolling bearings.
U309 washers are used in mechanical engineering as precisely fitting spacers and axial support surfaces for rolling bearings. The component is manufactured by SKF and is made of robust steel, enabling it to withstand axial compressive forces in mechanical assemblies. With an outer diameter of 90 mm and a width of 10 mm, the washer is suitable for bearing locations where a defined installation space needs to be bridged or a solid abutment surface for machine components needs to be created.
What is the u309 washer suitable for?
This washer is used where connecting structures require defined support or where roller bearings need to be fixed axially. Typical applications include bearing arrangements and general industrial drives where housing shoulders require reliable contact surfaces. The solid steel construction ensures that axial surface pressures are absorbed evenly. Maintenance engineers and designers use this component both in new designs and during scheduled maintenance work.
What is important to consider regarding the dimensions of the u309 shim?
When selecting this component, the focus is on ensuring a precise fit with the surrounding housing. The outer diameter of 90 mm determines the required radial installation space, whilst the washer width of 10 mm specifies the axial clearance in the bearing arrangement. As the component is made of high-strength steel, it is designed to withstand mechanical stresses during operation. Before installation, ensure that the contact surfaces of the housing stops are flat and free of particles.
What makes the u309 washers stand out?
U309 washers are axial bearing elements from SKF, manufactured from solid steel. They are used for precise axial positioning and force transmission in mechanical drives. Thanks to its solid material structure, the washer absorbs axial loads and protects adjacent housing sections from localised wear.
What are the dimensions of the u309 washer?
The component has an external diameter of 90 mm and a width of 10 mm. These dimensions are crucial for fitting into the housing bore and for determining the axial spacing between adjacent assemblies in mechanical engineering and gearbox construction.
What material are u309 washers made of?
SKF manufactures these washers from high-strength steel. The material offers high dimensional stability under axial loads and is suitable for demanding conditions in industrial applications, such as within lubricated housings.
What is the function of u309 washers in the bearing system?
The disc acts as a defined stop or spacer between roller bearings and housing walls. It transmits axial forces evenly to the surrounding structure and precisely compensates for axial clearances to ensure a controlled bearing fit.
What should be borne in mind when fitting the u309 washer?
Before installation, the mounting surfaces inside the housing should be thoroughly cleaned, as contaminants can affect the axial run-out. The disc, with an outer diameter of 90 mm, must sit flush so that axial forces are distributed evenly across the entire circumference.
