Decoding the designation

222 is the dimension series for a double-row spherical roller bearing. K is the bore form: a 1:12 tapered bore. W33 is the lubrication feature: an annular groove machined into the outer ring outside diameter with three radial holes drilled through to the roller path. Searchable forms of the number are 22215KVJW33, 22215 K VJ W33, 22215-K-VJ-W33 and 22215KVJ W33.

What these specs mean in practice

Dynamic Load Rating: 216 kN. Static Load Rating: 240 kN. Limiting Speed: 5,600 rpm. Maximum Temperature: 200°C. Minimum Temperature: −40°C. Two rows of spherical rollers running in a common concave outer raceway carry high radial load and take thrust in both directions, and the roller set swivels within the outer ring so the bearing tolerates shaft-to-housing misalignment without edge loading. On a double-row spherical roller bearing the static rating sits above the dynamic rating, which is the normal relationship for this type. CN is the standard radial internal clearance group. Harmonization Code: 8482.30.00.

Lubrication feature

Lubricant: Grease or oil. Relubrication: Yes, through the W33 provision. The groove distributes lubricant circumferentially around the outer ring and the three radial holes carry it inward to the rolling elements, so the roller path is fed from the outside diameter rather than through the ring faces. The same passages serve a grease gun, a single-point lubricator, a centralised grease line, a circulating-oil system or oil mist.

Bore form and mounting

The 1:12 tapered bore mounts on an adapter sleeve. Compatible adapter sleeve: H315, which seats on a 65 mm shaft and presents a 75 mm tapered outside diameter to match this bore. Driving the bearing up the sleeve taper sets the radial internal clearance by measurement rather than by shaft tolerance, and the assembly clamps with a KM locknut and MB lockwasher. A tapered bore also lets the bearing sit on a plain, unstepped shaft.

Quantity and configuration

Unit Quantity: 1 Pc. One complete bearing: inner ring, two rows of rollers with their cages, and the outer ring with the W33 groove and holes. The adapter sleeve is a separate part number.

Interchange guidance

Cross-Reference 1: SKF 22215 EK. Cross-Reference 2: FAG 22215E1.K. Both sit on the same 75 x 130 x 31 mm envelope with a 1:12 tapered bore and a lubrication groove, and both are reinforced E executions carrying higher load ratings than the figures published above. Take the rating from the designation actually fitted. A straight-bore 22215 on the same envelope is a related bore form rather than an interchange, because it mounts without a sleeve.
