811 Series Shaft Race (WS) and Housing Race (GS)

How to choose Bearing races

Points to check when selecting, with the values for this product (811 Series Shaft Race (WS) and Housing Race (GS)).

1. 1. Select the type suited to the application

   The LS is a general-purpose type made of hardened bearing steel with a ground raceway surface. The AS is a 1 mm thin-section type that allows both faces to be used as raceway surfaces. The WS (shaft side) and GS (housing side) have 811 series dimensions and suit high-speed applications requiring accurate centering. Determine the type based on rotational speed and centering accuracy requirements.

2. 2. Confirm compatible thrust bearings

   Select the raceway washer according to the model number of the bearing it will be combined with. The LS is compatible with AXK series shaft and housing raceway washers and AXW series housing raceway washers. The WS and GS are mainly for thrust cage-type cylindrical rollers and can also be combined with AXK series needle rollers. Verify using the compatibility table in the catalog.

3. 3. Match inner and outer diameters to shaft and housing

   The inner diameter d should match the shaft diameter, and the outer diameter D should match the housing bore or the bearing outer diameter. The applicable shaft diameter range for listed products is 4 to 160 mm. Shaft raceway washers and housing raceway washers guide on different sides (inner or outer diameter), so confirm the fit and clearance on the drawing.

4. 4. Consider thickness and rigidity of adjacent parts

   The thin-section AS type, at 1 mm thickness, reduces axial installation space and can be used even when adjacent parts are not hardened. However, because it is thin, check the flatness and supporting area of the supporting surface. The thicker LS type depends less on the supporting surface.

5. 5. Verify raceway durability by material and hardness

   The raceway surface must have sufficient surface hardness because it directly receives the contact load of the rollers. The LS uses hardened chromium bearing steel and the AS uses hardened spring steel. Check the material and hardness (HRC) values against load conditions and life requirements.

6. 6. Surface treatment according to operating environment

   In humid or wet environments, or when storage periods are long, check whether rust prevention treatment is applied. Rust on the raceway surface causes flaking and abnormal noise. Consider lubrication methods together with measures to prevent the lubricant from running out.
