This self-aligning ball bearing compensates for 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 is tapered at a ratio of 1:12 (bore type K), permitting mounting on a tapered shaft seat or with an adapter sleeve for a secure, adjustable fit. Bore diameter is 65.0 mm, outside diameter 120.0 mm, width 31.0 mm, and net mass 1.32 kg. The cage is TVH, a glass-fibre reinforced plastic cage. Limiting speed is rated at 5600.0 1/min, with a reference speed of 6200.0 1/min. Radial internal clearance corresponds to C3 (Group 3), greater than standard clearance, which accommodates thermal expansion and mounting-related preload on the tapered bore. The tapered bore and adapter-type fit make this bearing suitable for applications where precise axial positioning and easy dismounting are required, while the self-aligning design tolerates shaft deflection and housing misalignment. The plastic cage supports smooth ball guidance at the stated speed ratings without adding significant mass.
