This self-aligning ball bearing compensates for shaft misalignment through its spherical outer raceway, allowing the inner ring with balls to swivel relative to the outer ring. The bore diameter is 55.0 mm, outside diameter 120.0 mm, and width 43.0 mm, giving the mounting envelope for shaft and housing seats. Mass netto is 2.125 kg. The cage is made of reinforced plastic (TVH), and the limiting speed is 3750.0 1/min. Radial internal clearance is C3, greater than standard, which compensates for thermal expansion during operation. Integrated seals on both sides (2RS) retain grease and keep out contaminants, making relubrication during service unnecessary under normal conditions. The self-aligning design permits a degree of shaft deflection or housing bore misalignment without inducing additional internal stress on the balls or raceways.
