Two rows of balls run in a common spherical raceway in the outer ring, allowing the inner ring with balls and cage to swivel around the bearing centre and compensate for shaft misalignment and housing deflection. Bore diameter is 45.0 mm, outside diameter 100.0 mm, width 36.0 mm, net mass 1.21 kg. The cage is TVH, a solid plastic cage guided on the balls. Radial internal clearance is C3 (Group 3), wider than normal clearance. Limiting speed is 7000 1/min, reference speed 8000 1/min. The C3 clearance suits applications where shaft heating or interference fits reduce the operating clearance, while the self-aligning design tolerates angular misalignment between shaft and housing without inducing edge loading on the balls. The plastic TVH cage gives low friction and reduced mass compared with a solid cage, supporting the stated limiting and reference speeds. No bore relief or seal is specified, so lubrication and sealing must be provided externally through the surrounding housing.
