Decoding the designation

222 is the dimension series for a double-row spherical roller bearing. E is the reinforced design: larger rollers in a strengthened ring set, which raises load capacity over the plain execution on the same envelope. AS is the FAG lubrication code for a groove in the outer ring with radial feed holes, the same provision the ISO scheme writes as W33. M is the cage code: a machined brass cage. Searchable forms of the number are 22215EASMW33, 22215EAS.M, 22215 E AS M W33, 22215-E-AS-M-W33 and 22215E.AS.M.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. A machined brass cage is stiffer and more tolerant of high temperature, shock load and marginal lubrication than a pressed steel cage, and it carries acceleration and deceleration loads that would flex a sheet cage. CN is the standard radial internal clearance group. Harmonization Code: 8482.30.00.

Lubrication feature

Lubricant: Grease or oil. Relubrication: Yes, through the AS provision. The groove distributes lubricant circumferentially around the outer ring and the 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

Bore Type: Straight. The 75 mm cylindrical bore mounts directly on the shaft journal, and the mounted clearance follows from the shaft and housing fits.

Quantity and configuration

Unit Quantity: 1 Pc. One complete bearing: inner ring, two rows of rollers in machined brass cages, and the outer ring with the AS groove and feed holes.

Interchange guidance

Cross-Reference 1: SKF 22215 E. Cross-Reference 2: NTN 22215EMD1. Both sit on the same 75 x 130 x 31 mm envelope with a cylindrical bore and a reinforced design. Cage execution and load ratings differ between makers, so take the rating from the designation actually fitted. A 22215 K on the same envelope has a 1:12 tapered bore and mounts on an adapter sleeve, so it is a related bore form rather than an interchange.
