This spherical roller bearing carries two rows of asymmetrical rollers guided on a common sphered raceway in the outer ring, allowing the inner ring axis to tilt relative to the outer ring without loss of load capacity. Main dimensions follow DIN 635-2: bore diameter 80.0 mm, outside diameter 140.0 mm, width 33.0 mm, mass 2.065 kg. Limiting speed is 6200 1/min, reference speed 3550 1/min. The design is E1 with a cylindrical bore (bore type Z), a JPA cage, and C3 radial internal clearance (Group 3). The C3 clearance compensates for the temperature rise and fit-related clearance reduction typical of press fits, keeping the bearing free from excessive preload during operation. The self-aligning raceway geometry accommodates shaft deflection and housing misalignment, so the bearing tolerates angular displacement between shaft and housing without additional stress on the rollers. Standard relubrication feature supports periodic grease replenishment through the bearing during service, maintaining the lubricant film under continuous operation.
