1. The self aligning ball bearings consist of two rows of balls and a common concave sphered raceway in the outer ring and theinner ring.
2. This type bearings have the self-aligning capacity which make the bearings insensitive to angular misalignments of the shaft relative to the housing.
3. The series of the bearings: 1200, 1300, 2200, 2300 and so on.
4. The bearings are also available with a cylindrical bore or, in certain size ranges, with a tapered bore.
