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.

NRB Industrial (NIBL) Inner Rings have a precision ground raceway surface with a lead-in chamfer on both sides. The chamfers facilitate assembly and protect the seal lips from damage during the mounting process.

NRB manufactures Inner Rings with and without oil holes and with a convex outer diameter.
