An NTN angle ring is an auxiliary part in a cylindrical roller bearing arrangement. It is not a complete bearing, and selection depends on the assembly in which it operates. Record both the ring marking and associated bearing designation. Similar shape or shared numbers alone do not establish compatibility.

The catalog lists HJ204, HJ205, HJ206 and HJ204E. Retain the HJ prefix and any final letter when contacting MR. These examples belong to this line but are not a compatibility table for every cylindrical roller bearing of similar size or numbering.
For an unmarked ring, photograph its profile and both faces. Add measurable dimensions and the reference of the adjacent bearing. Do not infer a missing letter by comparing it with another loose part.
Identify the ring’s position within the support and the components on either side. An exploded drawing can show its relationship with the bearing ring and the parts locating the assembly on the shaft. This remains necessary even when only one auxiliary component is being replaced.
For previously repaired equipment, distinguish the arrangement found from the one shown on the drawing. An earlier modification is not automatically a confirmed specification. Record visible marks or damage on contact surfaces separately from replacement identification.
Request a quote with the NTN ring reference, bearing reference, quantity and machine position. Specify whether only the auxiliary part or other components are required. If several positions use similar rings, label photographs and associate each with its bearing to avoid mixing assemblies during review.
No. It is an auxiliary part; explicitly identify any additional required components.
No. Complete references and mounting documentation are needed.
The associated bearing designation and an exploded view help review ring shape and dimensions.

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.
The HJ angular ring is an auxiliary component that mounts on the inner ring of NU and NJ series cylindrical roller bearings. Its function is to retain the rollers axially and facilitate assembly of the unit, especially in applications where the bearing works with combined loads or where mounting requires precise position control. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina.
