AXK SERIES AXIAL ROLLER BEARINGLS-series axial roller bearing washer is designed for use with INA AXK-series axial needle roller and cage assemblies and INA K811-series axial cylindrical roller and cage assemblies in applications where adjacent components cannot serve as raceways and precise centering is not required. This axial bearing washer serves as a raceway surface for the thrust assembly's rolling elements and can be used as a housing locating washer (outer ring) centered in the housing or a shaft locating washer (inner ring) centered on the shaft. The raceway is ground to accommodate higher speeds and provide greater running accuracy than unground raceways. The washer is made of low alloy, through-hardened chromium steel for durability, heat tolerance, and resistance to deformity under heavy loads, and it can be used at operating temperatures from -20 degrees C to 120 C (-4 degrees F to 248 F). This axial bearing washer is suitable for use in various applications including machine tool drive shafts, automotive steering gears and clutches, rotary tables, outboard motor propellers, and household appliances.SpecificationsThrough-hardened steelISO 683-17Housing bore tolerance (when used as a housing washer)H9Shaft bore tolerance (when used as a shaft washer)h8System for creating part numbers for rolling bearingsDIN 623-1
