NSK 22228EXW33C3 is a double-row spherical roller bearing. Series: 22200. Bore: 140 mm. Outside Diameter: 250 mm. Width: 68 mm. Bore form: straight. Internal Clearance: C3. Cage: pressed steel. Closure: open. Searchable forms of the designation are 22228EXW33C3, 22228 EX W33 C3, 22228-E-X-W33-C3 and 22228EX W33 C3.
Bore form: straight, with no taper and no adapter sleeve in the mounting. W33: lubrication groove in the outer ring plus three radial feed holes. C3: internal clearance greater than normal. Precision Class: normal, ABEC 1 / P0.
A double-row spherical roller bearing carries heavy radial load and takes thrust in both directions. The self-aligning raceway absorbs shaft deflection and housing misalignment. C3 clearance leaves room for thermal growth on a shaft running warm or on an interference fit. The W33 groove and holes feed lubricant to the roller path from the housing, which suits relubrication in service on conveyors, fans, crushers and gearboxes.
Unit Quantity: 1 Pc. One complete bearing, two rows of rollers, pressed steel cage.
The straight bore mounts directly on a cylindrical shaft seat. Relubrication runs through the outer-ring groove and holes, so the housing feed port aligns with the groove.
SKF 22228 CC/C3W33 and FAG 22228-E1-C3 share the 140 x 250 x 68 mm envelope; the FAG number has no W33 groove in its designation. Related parts: NSK 22228K, the 1:12 tapered-bore version, which mounts on an H3128 adapter sleeve with a KM28 locknut and MB28 washer. Country of Origin: Japan.
