L-section Rings SKF HJ406

The SKF HJ406 angular ring, made of steel and measuring 30 × 50.5 × 11.5 mm, serves as an axial stop in roller bearing assemblies.

The HJ406 angular ring is a separate guide component for roller bearing assemblies and is manufactured by SKF. Made from steel, this accessory complements cylindrical roller bearings to absorb axial forces or to position components precisely. With a bore of 30 mm, an outer diameter of 50.5 mm and a width of 11.5 mm, the ring fits positively onto the inner ring of compatible bearings. Maintenance engineers and designers use this component to implement flexible bearing arrangements with clearly defined contact surfaces.

What is the HJ406 angular ring suitable for in practical applications?

The HJ406 angular ring is primarily designed to enable axial fixation of the shaft in one direction when used in combination with cylindrical roller bearings. The component forms an additional flange on the bearing inner ring, allowing radial and axial forces to be absorbed separately within the system.

Typically, the ring is used in shaft mountings where defined axial guide surfaces and tight fits on the shaft are required. By separating the bearing from the flange ring, assembly and disassembly can be carried out step-by-step and in a controlled manner during maintenance.

What is important when fitting the HJ406 angular ring?

When fitting the HJ406 angular ring, the most important factor is ensuring an exact match with the corresponding bearing and the shaft dimensions. The 30 mm bore requires a precise fit on the shaft, whilst the flat surface must lie flush against the inner ring to prevent wobbling.

Before assembly, check the connection dimensions and the correct installation direction of the flange. As the ring is made of steel, lubrication is provided via the adjacent bearing. Correct alignment protects the contact surfaces from one-sided wear.
