The NTN WA series 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, with self-aligning capability. It is used in equipment where the shaft may flex or misalign, such as conveyors, gearboxes, pumps and agricultural machinery. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina, and quotes it on WhatsApp with the complete code.

The designation of the WA series is read in blocks. WA identifies the NTN spherical roller series; the number that follows indicates the size (for example, 22207 corresponds to a 35 mm bore diameter). The suffixes EALLSKW33/8A provide design characteristics: EA is associated with an optimized roller and cage design; LL indicates sealing on both sides; SK is a lubrication groove and hole in the outer ring; W33 is the lubrication groove and three holes; /8A refers to a special execution. To order the exact code, pass it along complete as it appears on the equipment.

In Argentine industry, these bearings appear in belt conveyors, screens, mills, mixers, speed reducers and earthmoving equipment. They are also found in high-flow centrifugal pumps, industrial fans and machinery for the food industry. Their self-aligning capability makes them suitable for long shafts or shafts mounted in supports that may flex under load. MR Accesorios Industriales sells them for replacement and maintenance in plants in Buenos Aires, Argentina and the rest of the country.

To select the right bearing, take into account radial and axial load, rotation speed and the working environment. The WA series with the LL suffix incorporates seals that retain grease and block the entry of dust and moisture, ideal for dirty or humid environments. If the equipment works at high temperature or with centralized lubrication, the W33 groove and holes allow relubrication without disassembly. During mounting, verify the initial alignment and use the right tools so as not to damage the rollers or raceways.

NTN WA series spherical roller bearings can be interchanged with those of other brands that follow the same dimensional nomenclature, such as SKF, FAG, NSK or KOYO, as long as the bore, outer diameter and width, and the type of sealing, match. Interchangeability is not automatic: tolerances and service conditions must be compared. If you have the code from another brand, write to us on WhatsApp and we will tell you the equivalent compatible with your equipment.
