SKF spherical roller bearings of the 222 series with CCK, C3 or C4 and W33 suffixes are self-aligning bearings with two rows of rollers, tapered bore and stamped steel cage. They are used in applications with misalignment between shaft and housing, significant radial loads and some axial load. MR Accesorios Industriales sells this line for the Argentine industrial market.

The designation 22228 CCK/C3W33 reads as follows: 222 indicates the medium-width spherical roller bearing series; 28 is the size code; CCK defines the internal design with 1:12 tapered bore and stamped steel cage; C3 or C4 indicate the internal radial clearance, greater than normal; W33 indicates that the bearing has a lubrication groove and holes in the outer ring. Examples in the series include several sizes, with C3 or C4 and W33 combinations.

These bearings appear in mining, cement, steel, paper, aggregate processing and heavy transport equipment. They are found in conveyor belts, mills, crushers, screens, industrial fans and paper machines. In Argentina they are common in cement plants, quarries and the oilseed industry, where long shafts and welded structures require tolerating misalignment without losing load capacity.

To select correctly, take into account radial and axial load, speed, type of fit and internal clearance. The CCK tapered bore is mounted on a tapered shaft or adapter sleeve; C3 or C4 clearance is chosen according to working temperature and fit. Grease or oil lubrication must cover the W33 groove and holes. Initial alignment and sealing prevent contamination and extend service life.

Regarding equivalents, spherical roller bearings with tapered bore and similar suffixes are available from different brands, but internal codes and clearances do not always match. Do not replace by number without verifying dimensions, clearance and cage type. Interchangeability between manufacturers requires comparing tolerances and load capacities, not just diameter and width.
