The HJ angle ring is an auxiliary component that mounts on the inner ring of NU, NJ and NUP series cylindrical roller bearings. Its function is to retain the rollers axially and facilitate bearing disassembly, since it allows the inner ring with rollers to be removed without dismantling the assembly. It is made of bearing steel and is sold as a separate part for replacement or for use in assemblies that require additional axial guidance.

The HJ designation is completed by a number that indicates the size of the bearing it combines with. For example, HJ204 corresponds to a bearing of the 204 series, HJ205 to the 205 series, and so on up to HJ211. The number is not a direct measurement, but identifies the compatible bearing: the HJ ring is selected 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 keeps the same numeric 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 conveying equipment, and in general in any assembly with NU or NJ bearings that requires 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 it is intended for 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, since 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 bearing or ring code.
