For equipment where shafts deflect or bases settle, the SKF 22228 CCK/W33 spherical roller bearing offers a self-aligning, double-row solution that handles radial loads and axial loads in both directions. Its spherical outer raceway lets the shaft misalign while the bearing keeps working, which reduces mounting complexity and absorbs alignment errors.

This bearing belongs to the 222 series, a medium-section spherical roller line. The complete designation breaks down into useful blocks: 222 is the series, CC indicates two guide ribs and a central ring for roller guidance, K stands for a 1:12 tapered bore, and W33 means the outer ring has a lubrication groove and three holes. The same structure appears in sizes such as 22230 CCK/W33 and 22244 CCK/W33, so reading the code correctly is the first step to ordering the right replacement.

Typical applications include conveyor belts, mills, crushers, centrifugal pumps, industrial fans and paper machines. These are assemblies where heavy loads and misalignment are normal, and where perfect alignment between supports cannot be assumed. Large gearboxes and gear reducers also use this bearing type.

When selecting a variant, review the radial and axial load, the rotational speed and the lubrication method. The K suffix allows mounting with an adapter sleeve, which simplifies adjustment and disassembly. In dusty or wet environments, consider versions with additional seals or protectors. Grease or oil lubrication both work; with oil, the W33 groove and holes make relubrication easier. Careful initial alignment is still recommended, even though the bearing tolerates later misalignment.

Different manufacturers use their own designations, but standardized suffixes such as K and W33 are widely maintained. That makes interchange possible when dimensions and load capacities match. Always confirm the full part number and tolerances before substituting one brand for another. MR supplies the SKF brand and can advise on interchangeability.
