WS Series Axial Roller Bearing WS81208

WS-series axial roller bearing shaft locating washer is designed for use with INA K-series axial cylindrical roller and cage assemblies in applications where adjacent components cannot serve as raceways. This shaft locating washer (inner ring) is mounted on the shaft and serves as a raceway surface for the rolling elements. The raceway, bore diameter, and outside diameter are precision machined for tighter tolerances than unground surfaces. http://www.czh-bearings.com/
