Description
Inner rings are typically combined with needle roller and cage assemblies or drawn cup needle roller bearings in applications where the shaft cannot be hardened and ground. Also, Inner rings are a simple and quick solution to provide a counter-face for radial shaft seals without any hardening and fine machining of the shaft. The rings are simply pushed in position e.g. over a worn area. Inner rings together with radial shaft seals are a perfectly compatible sealing system. IR 131712.4 NRB
