JR25x30x20 Needle Roller Bearing Inner Rings SKF Needle Bearing Inner Ring Alternative

JR25x30x20 Needle Roller Bearing 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.

We can supply both standard K series models and interchangeable replacements compatible with INA, SKF, and IKO.
