The NTN spherical roller bearing is a component designed to withstand high radial loads and axial loads in both directions, with self-aligning capability. Its design with two rows of spherical rollers and a spherical raceway in the outer ring allows it to compensate for angular misalignment between shaft and housing, even under shaft deflection conditions. It is used in applications where alignment precision cannot be guaranteed, such as heavy machinery, conveyors and mining equipment. MR Accesorios Industriales sells this line.

The designation of these NTN bearings is interpreted from the series and the suffixes. For example, in ＊22208EMKD1, the prefix ＊ indicates that the bearing meets special NTN specifications. The number 22208 corresponds to the size and series: the 22 indicates the medium-section spherical roller series, and the last two digits indicate the bore diameter. The letter E indicates higher-capacity rollers, M machined brass cage, K tapered bore, and D1 an internal design variant. In ＊22308EMKD1, the 23 corresponds to the wider series. Knowing these suffixes allows you to select the right variant for each mounting.

These bearings are used in industries such as cement, mining, steel, paper and material handling. In Argentina, they are common in belt conveyors, mills, crushers, vibrating screens, cranes and process equipment. Their ability to withstand combined loads and misalignment makes them ideal for long shafts or mountings where structural rigidity is not complete. They are also used in industrial fans, pumps and large compressors. MR Accesorios Industriales offers them for replacement and new projects throughout the country.

To correctly select a spherical roller bearing, take into account the radial and axial load, the rotation speed, the lubrication and the sealing type. The tapered bore (suffix K) requires an adapter sleeve and a controlled interference fit; the internal clearance is adjusted according to the mounting method. Lubrication can be with grease or oil, and sealing will depend on the environment: open for oil bath, with plates or seals for contaminated environments. Initial alignment is less critical thanks to the self-aligning capability, but incorrect mounting can reduce service life. Follow the manufacturer's recommendations for fit and lubrication.

As for equivalents, NTN spherical roller bearings can be interchanged with those of other brands that follow the same dimensional nomenclature, such as SKF, FAG, NSK or Timken, as long as the type, series and suffixes match. However, load ratings and internal clearances may vary between manufacturers. If you need to replace an existing bearing, the safest approach is to identify the complete code engraved on the ring and consult a specialist. At MR we advise you to find the right equivalent without compromising performance.
