1.Don't increase the burden of the bearing. 2.Can adjust itself. 3.High quality with reasonable price.

1.It has two rows of balls and a common concave sphered raceway in the outer ring.

2.The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing.

3.It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected.

4.Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.
