IR-1312 Needle Bearing Inner Ring KOYO / NTN Interchange

IR-1312 Needle Bearing Inner Ring 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.
