This self-aligning ball bearing accommodates shaft misalignment through its spherical outer ring raceway, allowing the inner ring, balls, and cage to tilt relative to the outer ring axis. Bore diameter is 20.0 mm, outside diameter 47.0 mm, and width 18.0 mm, with a net mass of 0.134 kg. The limiting speed is 16300 1/min and the reference speed 15600 1/min, giving an indication of the thermal and mechanical speed capability of the bearing. The TVH cage is a glass-fibre reinforced plastic cage, guided on the balls, which contributes to smooth running at the stated speeds and reduces friction losses. Radial internal clearance is C3 (Group 3), providing a larger-than-normal clearance to compensate for thermal expansion or shaft deflection during operation. The bearing is suitable for applications where shaft misalignment or bending under load must be tolerated without inducing additional radial load on the rolling elements.
