This self-aligning ball bearing accommodates shaft misalignment through its spherical outer raceway, allowing the outer ring axis to tilt relative to the inner ring without inducing additional load. The bore diameter is 65.0 mm, outside diameter 140.0 mm, and width 33.0 mm, with a net mass of 2.41 kg. It features a tapered bore with a 1:12 taper (designation K), a plastic cage (TVH), and radial internal clearance in class C3. Limiting speed is 5200 1/min, with a reference speed of 5100 1/min. The tapered bore allows mounting on tapered shaft seats or with an adapter sleeve, simplifying fitting and enabling precise control of internal clearance during installation. The C3 clearance compensates for interference fit and thermal expansion during operation, while the TVH plastic cage reduces friction and mass compared to metal cages, supporting operation at the stated speed ratings. The self-aligning design tolerates shaft deflection and housing misalignment without increasing internal stresses, making the bearing suitable where precise shaft-housing alignment cannot be guaranteed.
