This self-aligning ball bearing compensates for shaft misalignment and deflection through its spherical outer raceway, allowing the inner ring, balls and cage to pivot relative to the outer ring. Bore diameter is 17.0 mm, outside diameter 40.0 mm, width 16.0 mm, and net mass is 0.087 kg. The bearing runs with a limiting speed of 19100 1/min and a reference speed of 17400 1/min, fitted with a glass fibre reinforced plastic cage (TVH) and cylindrical bore (Z). Radial internal clearance is in the normal CN (Group N) range, suitable for standard fit conditions without preload. The plastic cage design reduces friction and mass compared to metal cages, supporting the higher speed ratings listed above. Its self-aligning capability makes it suitable for applications where shaft bending or housing misalignment must be accommodated without inducing additional radial load on the bearing.
