This self-aligning ball bearing compensates for shaft misalignment and deflection thanks to its spherical outer raceway, allowing the inner ring, balls and cage to swivel around the bearing centre. It features a tapered bore (K) with a 1:12 taper, a bore diameter of 45.0 mm, outside diameter of 85.0 mm, width of 23.0 mm and a net mass of 0.502 kg. The cage is a glass-fibre reinforced plastic cage (TVH), and radial internal clearance corresponds to the normal CN (Group N) range. Limiting speed is 8600 1/min, with a reference speed of 7800 1/min. The tapered bore allows mounting directly on a tapered shaft seat or with an adapter/withdrawal sleeve, simplifying axial positioning and enabling controlled clearance reduction during fitting. The self-aligning design tolerates angular misalignment resulting from shaft bending or housing misalignment without inducing additional loading on the balls. The normal internal clearance (CN) is suited to standard operating conditions without extreme thermal or fit-related preload, and the polyamide cage (TVH) offers low friction and reduced weight compared with metal cages, supporting the stated limiting and reference speed values.
