When a shaft flexes under load or alignment between shaft and housing is less than ideal, the NTN WA series spherical roller bearing is built to handle it. Its double-row design runs on a spherical outer raceway, so it carries radial and axial forces in either direction while absorbing angular misalignment. Belt conveyors, mills, pumps and similar process equipment are common homes for this series. MR Industrial Accessories supplies it to maintenance and purchasing teams across the United States and Latin America.

Reading a WA part number is a matter of breaking it into blocks. WA is the NTN spherical roller series. The digits that follow give the bore: WA22208 is a 40 mm bore, WA22209 is 45 mm, and the pattern continues. Then come the execution codes: E for an optimized roller and cage design, ALLSKD for a special seal with built-in lubrication, and 1/8A to complete the assembly identification. A full reference such as WA22210EALLSKD1/8A or WA22215EALLSKD1/8A therefore pins down one exact combination of dimensions and execution.

These bearings suit equipment that sees heavy loads together with misalignment: belt conveyors, mills, mixers, centrifugal pumps, industrial fans, and machinery in cement, mining and steel production. Long shafts that deflect as they turn are a typical case, since a self-aligning bearing avoids the edge stresses a rigid bearing would suffer. Agricultural equipment and food processing plants also use them.

Selection starts with radial load, axial load, rotational speed and the surrounding environment. The ALLSKD seal keeps dust and moisture out and holds grease in, so check that it suits your lubricant type and operating temperature. During mounting, align the bearing and get the fits right on both shaft and housing; internal clearance has to be set according to diameter and application. Regular lubrication and regreasing at the right interval keep it running.

Spherical roller bearings can be swapped between manufacturers when the main dimensions, tolerances and execution (seal, cage, clearance) line up. Compare the complete part number, not just the basic number, and check the specifications. If you are holding another brand's reference or an unmarked bearing, send it to MR Industrial Accessories and we will identify the equivalent and quote it.
