The SKF HJ EC angle ring is an auxiliary part that fits onto the inner ring of NU series cylindrical roller bearings. It keeps the rollers in place axially, makes assembly easier, and can accommodate small axial loads in one direction. Manufactured to precise tolerances and heat treated for wear resistance, it is a practical choice for applications that need axial guidance and are taken apart often.
Reading the code: HJ stands for angle ring, while EC denotes an optimized design that uses a stamped steel cage and higher-capacity rollers. The digits in the middle—such as those in HJ 208 EC or HJ 216 EC—indicate the size of the bearing the ring fits, not the ring itself. So an HJ 212 EC pairs with an NU 212 EC bearing. Always confirm that the bearing suffix matches the ring's suffix to ensure proper fit.
These rings suit equipment where cylindrical roller bearings handle light axial loads and are disassembled frequently. Common settings include cement plants, steel mills, pulp plants, mining operations, and maintenance shops for gearboxes and pumps. They also appear in machine tools and transmission equipment that demand high axial rigidity. MR Industrial Accessories supplies them for both replacement and new projects.
When selecting a ring, consider the diameter and width of the corresponding NU bearing. Installation involves pressing the ring onto the inner ring; check that its face sits fully seated. Use the same lubrication as the bearing, and verify alignment to prevent lateral stresses. If the bearing has an EC cage, the ring must carry the same designation for dimensional interchangeability.
Other manufacturers may use similar designations like HJ or HJ EC, but tolerances or treatment can differ. No single standard governs these auxiliary parts, so it is wise to check critical dimensions before mixing brands. SKF is a brand that MR supplies, which provides traceability and quality. To replace an existing ring, compare the complete code and measurements.

Frequently asked questions
- What does the HJ EC designation mean?
- HJ indicates an angle ring and EC an optimized design with a stamped steel cage. The middle numbers correspond to the compatible bearing size; for example, HJ 208 EC goes with an NU 208 EC bearing.
- Can it be mounted on any cylindrical roller bearing?
- No, it is designed for NU series bearings with the EC suffix. The code and inner ring dimensions must match. Contact us with your bearing code and we will confirm compatibility.
- What care does mounting require?
- Press it onto the inner ring and verify that it seats well. Use the same lubrication as the bearing and check alignment. Avoid impacts that could deform the ring. If you have doubts, contact us on WhatsApp.
