1. There are two structures of self-aligning ball bearing - cylindrical bore and tapered bore, and the material of the cage includes steel, synthetic resin, and so on.
2. Its feature is the outer ring raceway is the spherical shape with self-aligning, which can compensate the errors caused by the self-aligning ball bearing with different aligning and deflection, but the relative inclination of the inner and the outer ring is not more than 3 degrees.
3. Between the inner rings of the two raceways and the outer ring taking the raceway as the spherical surface, the drum-shaped rollers are equipped in the bearing. Species: 1. Spherical ball bearing with Vertical Block 2. Spherical bearings with a square Block 3. With a spherical ball bearings in the diamond-shaped seat
4. With boss Round Block spherical ball bearings
5. Spherical ball bearings with annular seat
6. With a spherical ball bearings in the slider seat
7. Block with a suspended spherical ball bearings
