HJ Angle Ring for Bearings | NTN
The HJ angle ring is an auxiliary component mounted on the inner ring of cylindrical roller bearings of the NU, NJ and NUP series. Its function is to retain the rollers axially and facilitate bearing disassembly, as it allows the inner ring with rollers to be removed without dismantling the assembly. It is manufactured in bearing steel and sold as a separate part for replacement or to incorporate in assemblies requiring additional axial guidance.
