Self-aligning ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. Pressed steel cages are usually used.

Features:

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 sphere raceway.

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

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

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

Cage of the self aligning ball bearing is polyamide cage, steel cage.

suffix of the bearing:

Applications:

Self-aligning ball bearing is designed to withstand heavy load and impact load, precision instruments, low noise machine, automobile, motorcycle, metallurgy, rolling mill, mine, petroleum, papermaking, cement, the sugar industry, general machinery, etc.
