When a shaft deflects or the supports are not perfectly aligned, the SKF CC series spherical roller bearing is a common answer. It is a self-aligning unit with two rows of rollers that handles high radial loads while allowing angular movement between shaft and housing. Conveyors, mills, pumps and fans are typical homes for this series, and we supply it to maintenance and purchasing teams across the United States and Latin America.

Reading the code helps you pick the right unit. The leading digits give the size and dimension series, while the CC suffix tells you the bearing has a stamped steel cage guided by the rollers, plus special machining on the inner ring. Take the 21305 CC, 21306 CC and 21307 CC: same basic design, different main dimensions. The suffix does not alter load capacity, but it does affect limiting speed and how heat leaves the bearing. That is why knowing the nomenclature saves time at the counter or in front of the machine.

These bearings show up in cement, mining, steel, food processing and transport operations. You will find them on conveyor belts, ball mills, crushers, centrifugal pumps, industrial fans and paper machines. Wherever shaft deflection or imperfect support alignment exists, self-alignment keeps the assembly working. Combined loads are possible too, though the design is built around high radial loads.

Selection comes down to a few practical points. Open designs need external lubrication and suit clean areas; sealed versions, identified by suffixes such as 2RS or 2CS, keep dust and moisture out. Internal clearance matters as well: too much brings vibration, too little brings heat. Match the lubricant to the running speed and temperature. At mounting, set the initial alignment correctly and avoid impacts that could mark rollers or raceways.

For replacements, bearings that follow the same international designation, such as series 213, 222 or 223 with equivalent suffixes, can serve as alternatives. Even so, compare critical dimensions and tolerances, since internal clearance or cage design may differ. Send us the complete code of the original bearing and our team can review the interchange with you.
