HJ angle rings from SKF for cylindrical roller bearings

An angle ring designation mirrors the bearing's. HJ 208 EC is the ring for size 208 bearings of that variant, and HJ 212 EC for size 212. The letters after the number have to match the bearing's, because each ring suits one particular internal design.

If the designation adds a block after a slash, as HJ 312 EC/VA301 does, it goes with bearings of that same variant. HJ 1076 is from a different dimension series, for large bearings. A ring of another size or variant will not seat properly against the inner ring, even with a matching bore.

With a plain inner ring, a cylindrical roller bearing lets the shaft shift lengthwise both ways. Adding an angle ring limits that movement in one direction. When the inner ring already has a flange on one side, the angle ring covers the other side and the bearing locates the shaft in both directions. You get axial location without changing the bearing.

The ring must bear against the inner ring and be held on its other side by a shoulder, a nut or a spacer. Its axial load capacity is limited: it guides the shaft and is not meant for a heavy, steady thrust. Where thrust is high, the position calls for a different bearing type.

Send the ring designation and quantity. If you don't have it, the full designation of the cylindrical roller bearing it pairs with, every letter included, will do. Tell us which machine it goes on and whether the shaft has to be located in one direction or both. That lets us confirm whether a ring fits the case and which one.
