This spherical roller bearing accommodates radial loads together with angular misalignment between shaft and housing, using two rows of rollers running on a common spherical outer raceway. Main dimensions follow DIN 635-2: bore 140.0 mm, outside diameter 250.0 mm, width 68.0 mm, net mass 14.09 kg. Limiting speed is 3150 1/min, reference speed 2250 1/min. The bearing is executed in E1 design with a JPA cage and cylindrical bore (Z bore type). Radial internal clearance C3 (Group 3) is greater than normal clearance, compensating for interference fits and thermal expansion during operation. The larger clearance suits mounting conditions where the shaft or housing seat requires a tighter fit, while the self-aligning construction tolerates shaft deflection or misalignment without raising internal loading. Relubrication feature is standard, allowing grease replenishment through the bearing during service without disassembly.
