AS Series Bearing Washers for Cylindrical and Needle Roller Thrust Bearings

The AS Series bearing washers are precision-stamped, flat steel rings designed to act as raceways for needle or cylindrical roller thrust bearings. Due to their thin, space-saving design, they are especially suitable for applications with axial space constraints while still providing high load-carrying capacity.

Key Features

• Low-Profile Design: Minimizes axial space requirements without compromising performance.
• Dual Functionality: Can be used as either shaft washers or housing washers depending on assembly configuration.
• Hardened Steel Construction: Offers high wear resistance and ensures a long service life under heavy axial loads.
• Precision Ground Surfaces: Provide a smooth raceway for consistent rolling element motion and reduced friction.

Applications

AS series washers are widely used in:

• Automotive transmissions and gearboxes
• Industrial machinery and compact gear assemblies
• Electric motors and pumps
• Rotary actuators and machine tool spindles

Compatibility

AS washers are typically paired with needle roller thrust assemblies such as the AXK series or with cylindrical roller thrust bearing elements. When selected and assembled correctly, they help form a complete axial bearing solution capable of handling substantial axial loads in a compact footprint.

Conclusion

The AS Series Bearing Washers are essential components for high-performance axial bearing systems where space efficiency, load capacity, and low friction are critical. Their versatility and precision make them a popular choice in both standard and custom-engineered rotating systems.
