This spherical roller bearing carries two rows of rollers on a common spherical raceway in the outer ring, allowing angular compensation between shaft and housing. Main dimensions follow DIN 635-2: bore 130.0 mm, outside diameter 280.0 mm, width 93.0 mm, net mass 27.238 kg. The E1 design provides an optimized internal geometry for load distribution across the roller rows, the cage is executed in JPA, and the bore type is Z (cylindrical). Limiting speed is 2650 1/min, reference speed 1820 1/min. Radial internal clearance C4 (Group 4) is above normal, compensating for the tighter fit and thermal expansion typical of interference-fit mounting on the shaft, and keeping proper operating clearance once the bearing reaches working temperature. Relubrication follows the standard feature, so grease can be replenished through the regular lubrication points during service. The self-aligning capability inherent to this construction allows the bearing to accommodate shaft deflection and initial misalignment without additional external compensation.
