The SKF CC series spherical roller bearing is a self-aligning bearing with two rows of rollers, designed to withstand high radial loads and angular misalignment between shaft and housing. Its design allows the shaft to flex without generating additional stresses, making it ideal for equipment with long shafts or assemblies where perfect alignment is not guaranteed. It is used in demanding industrial applications, such as conveyor belts, mills, pumps and fans. At MR Accesorios Industriales we supply this series with SKF quality.

The CC series designation is interpreted as follows: the first digits indicate the size and dimension series, while the CC suffix indicates a stamped steel cage, roller-guided, and special machining of the inner ring. For example, the 21305 CC, 21306 CC and 21307 CC share the same basic design but vary in their main dimensions. The CC suffix does not change the load capacity, but it does influence the limiting speed and heat dissipation. Knowing this nomenclature allows you to quickly identify the bearing's characteristics and select the right one for your equipment.

These bearings are used in a wide variety of industries in Argentina, such as cement, mining, steel, food and transport. They are common in conveyor belts, ball mills, crushers, centrifugal pumps, industrial fans and paper machines. Their ability to withstand misalignment makes them suitable for equipment subject to shaft deflection or assemblies where the supports are not perfectly aligned. They are also used in applications with combined loads, although their specialty is high radial loads.

When selecting a spherical roller bearing, take into account the type of sealing: open designs require external lubrication and are suitable for clean environments, while sealed versions (with suffixes such as 2RS or 2CS) protect against dust and moisture. Internal clearance is also critical; excessive clearance can cause vibrations and insufficient clearance can cause overheating. Lubrication must be suitable for the operating speed and temperature. During mounting, ensure correct initial alignment and avoid impacts that could damage the rollers or raceways.

Regarding equivalences and interchangeability, SKF CC series spherical roller bearings can be replaced by products from other manufacturers that follow the same international designation, such as series 213, 222, 223, etc., with equivalent suffixes. However, always verify the critical dimensions and tolerances, as there may be differences in internal clearance or cage design. For a safe replacement, consult our technical team and provide the complete code of the original bearing.
