SKF spherical roller bearings are self-aligning bearings with two rows of rollers and a spherical raceway in the outer ring. They absorb high radial loads and axial loads in both directions, and tolerate angular misalignment between shaft and housing. They are used in equipment where shaft deflection or mounting errors are part of everyday operation: power transmission, pumps, fans, conveyors and process machinery. MR Accesorios Industriales sells them as a brand.

The designation of these bearings is read in blocks. The base number, as in 22213, indicates the dimension series: the first digit defines the type and the following digits the size. The letter E indicates a higher load capacity design within that series. The suffixes come after: C3 is the increased internal radial clearance, intended for fits with tight interference or thermal rise, and W64 identifies a particular execution variant defined by the manufacturer. The complete code, then, is interpreted from left to right: series, design and variants.

In Argentine industry they appear in continuous-motion equipment: conveyor belts, bucket elevators, mills, mixers, centrifugal pumps, industrial fans and gearboxes. Also in road machinery, cranes and sheet metal equipment. The reason is simple: where the shaft deflects or the housing is not perfectly aligned, a rigid bearing works under stress and fails earlier. The spherical roller bearing accommodates that misalignment without losing load capacity, which is why it is a frequent choice in maintenance and replacement of equipment already in the plant.

To select correctly, look at three things. First, internal clearance: if the mounting has an interference fit on the shaft or there is a thermal gradient, a C3 clearance prevents the bearing from becoming preloaded. Second, sealing: open executions require controlled lubrication and cleanliness; if there is dust, water or washdown, it is advisable to evaluate variants with seals or shields. Third, lubrication and alignment: grease or oil depending on speed and temperature, and verify that the housing and shaft are within the permissible misalignment. Mounting with blows or without suitable tools shortens service life.

Regarding interchangeability, spherical roller bearings follow dimension standards that allow replacing one brand with another if the base number and the clearance and execution suffixes match. But be careful: not all manufacturers use the same letters for the same thing. A C3 may correspond to a different suffix in another brand, and a sealed execution may not have an exact equivalent. Before changing brands, compare bore, outside diameter, width, clearance and sealing type. If you have doubts, send us the old and new codes.

If you are replacing a spherical roller bearing, send the complete code by WhatsApp to MR Accesorios Industriales. With the base number and suffixes we confirm the variant and send you the quote. If you don't have it at hand, a photo of the marking or the shaft and housing measurements are enough to guide you. We work with SKF.
