Description

This self-aligning ball bearing accommodates shaft misalignment and deflection through its two-row spherical raceway design. The bore diameter is 100.0 mm, outside diameter 180.0 mm, and width 34.0 mm, with a net mass of 3.833 kg. It features a tapered bore with a 1:12 taper (K), a solid brass cage (M), and radial internal clearance C3, which is greater than standard clearance. Limiting speed is rated at 6000.0 1/min, with a reference speed of 4500.0 1/min. The tapered bore allows mounting on adapter or withdrawal sleeves, simplifying fitting on plain shafts and enabling clearance adjustment during installation. The C3 internal clearance compensates for interference fit effects and thermal expansion during operation, while the solid brass cage provides stable ball guidance at the given speed range. The self-aligning design permits angular shaft deflection without inducing additional load on the raceways, making this bearing suitable for applications where shaft bending or housing misalignment must be tolerated.
