This self-aligning ball bearing carries two rows of balls running on a spherical raceway in the outer ring, allowing the outer ring axis to tilt relative to the inner ring. Bore diameter is 110.0 mm, outside diameter 200.0 mm, width 38.0 mm, and net mass 5.27 kg. The bore is machined to a 1:12 taper (bore type K) for mounting on a tapered seat or with an adapter/withdrawal sleeve. The cage is a solid brass cage (designation M). Limiting speed is 5300 1/min, reference speed 4200 1/min, and radial internal clearance is C3, greater than normal. The tapered bore lets the bearing be fitted with a controlled interference by axial displacement on the shaft or sleeve, which is convenient where frequent mounting and dismounting is required. Self-aligning capability compensates for shaft deflection and housing misalignment, reducing edge loading on the balls and raceways. The C3 clearance offsets the clearance reduction caused by the interference fit and by temperature rise in operation, keeping the internal clearance within the intended working range. The solid brass cage gives stable ball guidance at the stated speed values and under the alignment conditions this design is intended for.
