This spherical roller bearing carries radial loads and accommodates angular misalignment between shaft and housing through its two rows of rollers running on a common sphered outer raceway. Main dimensions follow DIN 635-2: bore 150.0 mm, outside diameter 270.0 mm, width 96.0 mm, net mass 23.581 kg. The limiting speed is 2400 1/min, reference speed 1400 1/min, with design E1A and cylindrical bore (Z). The C3 radial internal clearance provides additional internal play to compensate for thermal expansion and interference fit during operation, and the M cage (machined) supports steady guidance of the rollers at the stated speeds. Standard relubrication feature allows relubrication during service without dismantling the bearing. This construction suits applications with shaft deflection or housing misalignment, where a self-aligning bearing seat is required.
