INA GS81111 Housing Positioning Disc for Cylinder Needle Roller Axial Bearings

The INA GS81111 is a precision-ground housing thrust washer that serves as an outer race for axial cylindrical roller bearings or axial needle roller bearings. It is used when the adjacent housing surface cannot be used as a raceway. Made of hardened rolling bearing steel, it ensures high dimensional accuracy, reliable guidance, and secure accommodation of axial forces. It is particularly suitable for axial roller bearings of the INA series 811 (e.g. 81111-TV).
