REXNORD spherical roller bearings are built to carry heavy radial loads and moderate axial loads in both directions, even when the shaft is misaligned. Their double-row roller design and spherical outer raceway let them adjust to shaft deflection without sacrificing load capacity. You will find them in conveyors, gearboxes, pumps and other process equipment where perfect alignment is not realistic.

The part number combines a four-digit base number with the suffix YU, which denotes the Rexnord spherical roller configuration. Examples include 5403YU, 5407YU and 5408YU from the 5000U series, and 9311YU, 9315YU and 9400YU from the 9000U series. Within each series, a higher base number means a larger bore and a more robust bearing. The YU suffix points to construction details specific to Rexnord for this family, including sealing and mounting features that should be verified for your application.

These bearings appear in food processing, cement, mining, paper and material handling operations. They are common in belt conveyors, bucket elevators, mixers, speed reducers, centrifugal pumps and other equipment where loads are high and shaft deflection can occur. Because they self-align, they work well in split plummer block housings and on long shafts that bend under load. MR supplies them for both replacement and new projects.

When selecting a bearing, consider the radial and axial loads it will see, the rotation speed, the shaft diameter and the operating environment. Sealing is critical: in dusty, wet or washdown conditions, reinforced protection is advisable. Lubrication must match the temperature and speed; high-viscosity grease is often used. During mounting, keep everything clean, align initially and use a fit that still allows the bearing to self-align. Avoid direct impacts on the rollers and check internal clearance after installation.

Spherical roller bearings are identified by their full designation, including series, base number and suffixes. For a replacement, diameter and width alone are not enough: you must also match the sealing configuration, internal clearance and cage type. Other brands such as SKF, FAG, NSK or Timken use their own nomenclatures, but interchangeability is determined by comparing dimensions and capacities. If you are unsure, send us the original part number and we will point you to a compatible alternative.
