This spherical roller bearing accommodates two rows of rollers guided on a common sphered raceway in the outer ring, allowing the inner ring, rollers and cage to swivel relative to the outer ring and compensate for shaft misalignment and housing deflection. Bore diameter is 80.0 mm, outside diameter 170.0 mm, width 39.0 mm, and mass 4.42 kg. The limiting speed is 5700 1/min, with a reference speed of 4050 1/min. It features a cylindrical bore (bore type Z), a JPA cage, the E1 design, and radial internal clearance in the CN (Group N) range. The CN clearance combined with the misalignment capability of the spherical raceway makes this bearing suitable for applications where shaft deflection or alignment inaccuracies must be tolerated without inducing additional internal stresses. The E1 design provides an optimized internal geometry for load distribution, and the JPA cage supports smooth roller guidance at the stated speed range. Standard relubrication feature allows grease replenishment during service without disassembly.
