Thrust is carried in both directions. The bore is cylindrical, so the bearing mounts straight onto a ground shaft seat. Internal Clearance: CN, the normal class, which suits an interference fit on the shaft with a standard housing fit.

Interchange guidance

Cross-Reference 1: SKF 22215 E. Cross-Reference 2: FAG 22215-E1-XL. Both share the 75 x 130 x 31 mm envelope and the cylindrical bore. A 22215K carries a 1:12 tapered bore and mounts on an adapter sleeve instead of directly on the shaft, so it is a related size rather than a substitution.
