The NTN spherical roller bearing is a self-aligning bearing with two rows of rollers, designed to withstand high radial loads and axial loads in both directions. Its spherical outer raceway allows the shaft to misalign without losing functionality, making it ideal for applications with shaft deflection or assemblies where perfect alignment is not guaranteed. It is available in versions with cylindrical or tapered bore, with different sealing systems and cages.

The series designation combines letters and numbers that indicate key features. For example, in ＊22205EMKW33, the prefix ＊ indicates a special execution, 22205 is the size code, E indicates higher-capacity rollers, M refers to the machined brass cage, K to the tapered bore and W33 to the lubrication groove and holes in the outer ring. Suffixes may vary depending on the configuration: steel cages, seals or shields. Knowing these codes helps you choose the correct variant for each application.

These bearings are used in mining, cement, steel, pulp and paper equipment, and in the food industry. In Argentina, they are common in conveyor belts, mills, mixers, centrifugal pumps and industrial fans. Their ability to withstand misalignment makes them suitable for long shafts and assemblies where thermal or load deformations generate small angles between the shaft and the housing. They are also used in applications with vibration or moderate impact loads.

To select the right bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. If there is contamination, choose versions with seals or shields. The tapered bore (suffix K) requires an adapter sleeve and allows the internal clearance to be adjusted. Lubrication must be adequate: grease or oil depending on speed and temperature. During mounting, ensure correct initial alignment and avoid impacts that could damage the rollers or raceways.

NTN spherical roller bearings are interchangeable with those of other brands that follow the same dimensional nomenclature, such as SKF, FAG, NSK or Timken. However, always verify tolerances and internal clearance, as they may vary between manufacturers. If you replace a bearing, compare the suffixes to maintain the sealing, cage and lubrication characteristics. MR Accesorios Industriales advises you to find the correct equivalent according to the original code.
