The self-aligning ball bearing 2305-TVH-C3 has two rows of balls running on a common spherical raceway in the outer ring, which allows the outer ring axis to tilt relative to the inner ring. Bore diameter is 25.0 mm, outside diameter 62.0 mm, width 24.0 mm, mass 0.334 kg. Limiting speed is 12200 1/min, reference speed 11900 1/min. The cage is TVH (plastic), radial internal clearance is C3 (Group 3), bore type Z. The self-aligning construction allows the bearing to compensate for shaft deflection and housing misalignment without additional radial load on the balls. The C3 clearance offsets the reduction in internal clearance from an interference fit or thermal expansion during operation. The plastic TVH cage reduces mass and friction, supporting the stated limiting and reference speeds. As an open bearing, it requires external sealing and periodic relubrication of the raceways and balls.
