JR50x55x20 Needle Roller Bearing Inner Rings KOYO / NTN Interchange

JR50x55x20 Needle Roller Bearing Inner Rings is a precision ground, through-hardened component designed for use with K series needle roller and cage assemblies or HK series drawn cup bearings. They provide a hardened raceway when the shaft cannot serve this function.

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