This self-aligning ball bearing combines a spherical outer raceway with two rows of balls, allowing the inner ring, balls and cage to tilt relative to the outer ring. Bore diameter is 50.0 mm, outside diameter 110.0 mm, width 40.0 mm, and net mass 1.64 kg. Limiting speed is 4000 1/min, with radial internal clearance in class CN (Group N). The cage is a solid plastic TVH type, both sides carry 2RS contact seals, and the bore type is Z, indicating a cylindrical bore. The spherical raceway lets the bearing accommodate shaft misalignment and deflection without generating additional radial load, while the CN clearance keeps operating play within the standard range for typical fits and thermal expansion. The plastic TVH cage lowers friction and mass, supporting steady running up to the stated limiting speed. Integrated
