Description

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 designation is completed with a number indicating the size of the bearing with which it is combined. For example, HJ204 corresponds to a bearing of series 204, HJ205 to series 205, and so on according to the code. The number is not a direct measurement, but identifies the compatible bearing: the HJ ring is chosen according to the code of the cylindrical roller bearing to be mounted. In cases where the bearing has suffixes, such as NU or NJ, the HJ ring maintains the same numerical reference.
This type of ring is used in applications where the cylindrical roller bearing must support axial loads in one direction and, at the same time, allow frequent disassembly. It is common in gearboxes, industrial pumps, machine tools, mining and transport equipment, and generally in any assembly with NU or NJ bearings requiring axial retention. In Argentina, it is found in equipment maintenance in the food, petrochemical and steel industries.
To select the correct HJ ring, the cylindrical roller bearing for which it is intended must be identified. The number following HJ must match the bearing code: an HJ208 goes with a 208 bearing. It is important to verify that the bearing is of the appropriate series, as the ring rests on the inner ring and must fit into the corresponding groove. During mounting, it is recommended to lubricate the contact surface and ensure correct alignment to avoid premature wear.
NTN HJ rings are interchangeable with those of other brands that manufacture cylindrical roller bearings with the same designation. If the customer has the code from another brand, the NTN equivalent can be quoted. Interchangeability is based on the standardized dimensions of the bearing, so an HJ from one brand can replace that of another as long as the base bearing is the same. To confirm equivalence, simply send the complete code of the bearing or the ring.
At MR Accesorios Industriales we sell NTN HJ angle rings for the entire line of cylindrical roller bearings. If you need an HJ204, HJ205 or any other size in the series, write to us via WhatsApp with the bearing or ring code and we will quote it promptly. We can also advise you on compatibility with the bearings you already have mounted.

Frequently Asked Questions
- How do I know which HJ ring I need?
- The HJ ring number must match the cylindrical roller bearing code. For example, for a 208 bearing, the ring is HJ208. If in doubt, send us the bearing code via WhatsApp and we will indicate the corresponding ring.
- Is the HJ ring compatible between different brands?
- Yes, NTN HJ rings are interchangeable with those of other brands that manufacture cylindrical roller bearings with the same designation, as the dimensions are standardized. To confirm equivalence, send us the ring or bearing code and we will quote the replacement.
- What function does the HJ ring perform in the bearing?
- The HJ ring is mounted on the inner ring and serves to retain the rollers axially and facilitate bearing disassembly. It allows the inner ring with rollers to be removed without dismantling the entire assembly, which simplifies maintenance.
