Decoding the designation

222 is the double-row spherical roller medium width series and the bore code 13 gives a 65 mm bore. EA marks the reinforced high-capacity execution with a pressed steel cage. There is no K in the designation, so the bore is straight and mounts directly on a cylindrical shaft seat. B33 is the SNR form of the W33 lubrication feature — an annular groove machined in the outer ring outside diameter with three radial holes through to the rolling elements. J30 is the SNR clearance code for C3, a radial internal clearance wider than normal. The part is also marked 22213 EA B33 J30 and 22213 EA W33 C3.

What these specs mean in practice

Two rows of barrel-profile rollers run on a common sphered outer raceway, so the bearing takes up angular misalignment between two shaft supports while carrying heavy radial load and thrust in either direction. Limiting Speed: 5300 rpm. Maximum Operating Temperature: 200°C. C3 clearance covers the running clearance consumed by an interference inner-ring fit and by a shaft running hotter than its housing, which is the usual condition in gearbox, fan and conveyor service.

Lubrication feature

Relubrication: B33 — an outer-ring lubrication groove with three radial holes, the SNR equivalent of W33. Lubricant: grease or oil. The groove distributes lubricant circumferentially around the outer ring and the three radial holes carry it inward to the centre of the roller path.

Bore form

Bore Type: Straight, 65 mm cylindrical. The bearing seats directly on the shaft journal, with no adapter sleeve in the mounting.

Quantity and configuration

Unit Quantity: 1 Pc. One complete double-row spherical roller bearing, open on both faces.

Interchange guidance

Cross-Reference: SKF 22213 E/C3, FAG 22213E1.C3. Both are straight-bore 22213 executions at C3 clearance on the same 65 x 120 x 31 mm envelope. Harmonization Code: 8482.30.00.
