1) This kind of bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing.

2)The self-aligning ball bearing are made of an inner ring, an out ring, two rows of balls, and a cage. Usually the outer ring of the bearing has a sphered raceway.

3)The material of the cage of the self aligning ball bearing is polyamide or steel.

4)The inner ring of the self-aligning ball bearing are usually cylindrical, and sometimes are taper ring, which has the sufix of “k”.

5) The self-aligning ball beaing is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected.

6)sufix of the bearing has different means:
