Decoding the designation

222 is the double-row spherical roller series and the bore code 13 gives a 65 mm bore. V is the SNR internal design generation immediately preceding the ULTAGE E design: symmetrical rollers, no central inner-ring rib, lateral retaining shoulders holding the rollers, and rings stabilised for service to 200°C. B33 is the SNR form of the W33 lubrication feature — a groove and three holes through the outer ring. J30 is the SNR clearance code for C3, greater than normal. There is no K, so the bore is straight cylindrical. The part is also marked 22213 V B33 J30, 22213VW33C3 and 22213 V C3 W33.

What these specs mean in practice

The sphered outer raceway lets the inner-ring assembly swivel, so the bearing accommodates shaft deflection and housing misalignment without edge-loading the raceways. Maximum Permissible Misalignment: 1.5°. Both roller rows carry very high radial load and take axial load in either direction. Dynamic Load Rating: 193 kN (43,388 lbf). Static Load Rating: 216 kN (48,558 lbf). Limiting Speed: 6300 rpm. Maximum Operating Temperature: 200°C. Rings stabilised to 200°C hold their dimensions at sustained high temperature rather than growing and consuming operating clearance, which is why this design appears in fans, dryers and kiln drives as well as ordinary gearboxes. C3 clearance absorbs a heavy interference fit on the shaft, a large temperature difference between the rings, and thermal growth in the housing.

Lubrication feature

Relubrication: B33 — a lubrication groove machined in the outer ring outside diameter with three holes through to the rolling elements, the SNR equivalent of W33. Lubricant: grease or oil. The groove distributes lubricant circumferentially around the outer ring and the three holes carry it inward to the centre of both roller rows, which is what lengthens relubrication intervals on this size.

Bore form and mounting data

Bore Type: Straight, 65 mm cylindrical. Locking Method: interference fit on a cylindrical shaft seat. Chamfer rs min: 1.5 mm. Fillet ras max: 1.5 mm. Shaft abutment da min: 74 mm. Housing abutment Da max: 111 mm. Axial load factors for the 22213 envelope: e 0.24, Y1 2.79, Y2 4.15, Y0 2.73.

Quantity and configuration

Unit Quantity: 1 Pc. One complete non-separable bearing — inner ring, two rows of symmetrical rollers, steel cage, and outer ring with the lubrication groove and three holes.

Interchange guidance

The 65 x 120 x 31 mm 222-series envelope is an industry standard, so a 22213 in another maker’s nomenclature fits the same seat. Cross-Reference: SKF 22213 CC/C3W33 and 22213 E/C3W33, FAG 22213-E1-C3, NSK 22213CDE4C3, NTN-SNR 22213EAW33C3, Timken 22213EJW33C3, Koyo 22213RHW33C3, RHP 22213EJW33C3. The NTN-SNR 22213EAW33C3 is the later ULTAGE generation of the same bearing and is rated higher, at 226 kN dynamic. The 22213KVB33J30 is a related size with a 1:12 tapered bore, which mounts on an H313 adapter sleeve. Harmonization Code: 8482.30.
