JR90x105x32 Inner Rings KOYO / NTN Interchange

JR90x105x32 Inner Rings is a precision-machined, hardened, and ground component that serve as the inner raceway for needle roller and cage assemblies (K series) or drawn cup needle roller bearings (HK/BK series). They are used when the shaft itself cannot be hardened and ground to the required specifications for direct raceway use.

Custom orders are welcome, and interchangeable replacements for common international brands (INA,FAG,KOYO,NTN SKF, IKO) are also available.
