Supplies both inner rings for needle roller bearings and needle rollers as separate needle roller bearing components.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.

Needle rollers can be used to design full complement bearing arrangements for low-speed or oscillating applications. These compact bearing arrangements have a very high load carrying capacity when compared to bearings with a cage and are economical, provided the shaft and housing bore can serve as raceways (Raceways on shafts and in housings).Inner rings are used in industrial, production and agricultural equipment for a variety of applications. Grainger offers precision ground inner rings in a range of bore sizes and diameters to accommodate a spectrum of shaft and housing sizes.
