SNR22213EAB33J30Spherical Roller Bearing – Double Row, Straight Bore, 65 mm ID, 120 mm OD, 31 mm Width, Open, W33 Lubrication Groove, C3 Internal Clearance

Product Description

What this part is: SNR 22213EAB33J30 double-row spherical roller bearing. Series: 22200. Base Number: 22213. Bore: 65 mm. Outside Diameter: 120 mm. Overall Width: 31 mm. Number Of Rows: 2. Rolling Elements: Spherical Roller. Bore Type: Straight (cylindrical). Closure Type: Open. Cage Material: Pressed Steel. Cage Type: Pressed. Internal Clearance: C3. Precision Class: ABEC 1 / ISO P0. Bearing Material: Bearing steel. Item Weight: 3.40 lb (1.54 kg). Design Units: Metric. Unit Quantity: 1 Pc. GTIN: 3413520082925. 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.
