The NTN spherical roller bearing is a self-aligning component with two rows of rollers, designed to withstand high radial loads and axial loads in both directions, even with misaligned shafts. Its spherical outer raceway allows the assembly to self-align, absorbing mounting errors or shaft deflections. It is used in industrial applications where the load is heavy and alignment conditions are not perfect, such as transmissions, pumps, fans and process equipment. MR Accesorios Industriales sells it in Buenos Aires, Argentina.

The series designation combines letters and numbers that indicate key features. For example, in 22205EAKW33, the prefix 222 corresponds to the medium-section spherical roller series; 05 indicates the bore diameter (multiplied by 5); EA identifies an optimized internal design; K indicates a tapered bore (taper 1:12); and W33 refers to the lubrication groove and holes in the outer ring. The examples 22206EAKW33 and 22207EAKW33 follow the same logic, varying in size. Knowing these suffixes allows you to choose the right variant for your equipment.

These bearings are used in industries in Argentina such as cement, mining, steel, paper and food. They are present in gearboxes, conveyor belts, mills, screens, centrifugal pumps, industrial fans and continuous process machines. Their ability to withstand combined loads and misalignment makes them ideal for equipment subject to vibrations or assemblies where exact alignment is difficult to achieve. MR Accesorios Industriales offers them for replacement and maintenance of critical machinery.

To select correctly, take into account the radial and axial load, the rotation speed and the type of lubrication. The tapered bore variant (K) requires a suitable adapter sleeve, which ensures a firm fit and facilitates disassembly. The W33 suffix indicates lubrication grooves that allow relubrication of the bearing without disassembling the equipment. Check the internal clearance and sealing according to the environment: dust, humidity or high temperatures require additional protection. Careful initial alignment extends service life, although the self-aligning design tolerates certain deviations.

Regarding equivalences, spherical roller bearings are manufactured under international standards that allow brands to be interchanged while maintaining the same main dimensions and load capacity. If you need to replace a bearing from another brand, compare the complete designation: series, bore diameter, bore type and lubrication suffixes. At MR Accesorios Industriales we quote the exact code you need, with the NTN designation or the compatible alternative.
