The NTN WA series spherical roller bearing is a double-row oscillating roller bearing with a spherical raceway on the outer ring. It is designed to withstand radial and axial loads in both directions, and it tolerates angular misalignment between shaft and housing. It is used in equipment with shaft deflection or difficult mounting, such as conveyors, mills, pumps and process machinery. MR Accesorios Industriales sells the NTN WA series in Buenos Aires, Argentina.

The WA series designation is read in blocks: WA identifies the NTN spherical roller series; the following numbers indicate the bore diameter (for example, WA22208 corresponds to 40 mm, WA22209 to 45 mm, and so on). The suffix E indicates an optimized roller and cage design; ALLSKD refers to a special seal and built-in lubrication; 1/8A completes the assembly identification. Each part number, such as WA22210EALLSKD1/8A or WA22215EALLSKD1/8A, defines a specific combination of dimensions and execution.

In Argentine industry, these bearings are used in equipment subjected to heavy loads and misalignment: belt conveyors, mills, mixers, centrifugal pumps, industrial fans and machinery for cement, mining and steelmaking. Their self-aligning capability makes them suitable for long shafts that deflect under load, where other rigid bearings would fail due to edge stresses. They are also found in agricultural applications and in food processing plants.

To correctly select a spherical roller bearing, take into account the radial and axial load, the rotational speed and the environment. The ALLSKD seal protects against dust and moisture, and retains the lubricant; verify that it is compatible with the type of grease and the temperature conditions. Mounting requires initial alignment and a proper fit on the shaft and housing; internal clearance must be controlled according to the diameter and the application. Correct lubrication and periodic regreasing extend service life.

Spherical roller bearings are interchangeable between manufacturers if the main dimensions, tolerances and execution (seal, cage, clearance) match. When replacing an NTN with another brand, compare the complete part number and the technical specifications; the basic number alone is not enough. If you have another brand's part number or an unidentified part, at MR Accesorios Industriales we tell you the compatible equivalent and quote the option you need.
