Structural composition of self-aligning ball bearings

1. Outer ring:

● The raceway surface of the outer ring is spherical, and the center of curvature is consistent with the center of the bearing, which has the ability to automatically align the heart.

● The outer ring is usually made of high-carbon chromium bearing steel, and has high hardness and wear resistance after heat treatment.

2. Inner ring:

● The inner ring has a cylindrical or conical hole and is used in conjunction with the shaft.

● The inner ring is also made of high-carbon chromium bearing steel, and the surface is hardened to improve wear resistance and fatigue resistance.

3. Rolling element (ball):

● Spherical balls are located between the inner and outer rings and bear the main radial load.

● The rolling element is usually made of high-carbon chromium bearing steel, and has high hardness and precision after precision machining and heat treatment.

4. Cage:

● Used to keep the position of the rolling element and prevent it from falling off.
