The centering characteristics of heavy duty bearing pedestals are generally composed of four parts: the inner ring, the outer side, the stamping die, and the cage. The actual effect of the inner ring is to fit and rotate with the shaft like a shaft; The actual effect of the outer side is to complement the bearing with a seat and play a practical role in supporting the point; The stamping die distributes the stamping die symmetrically between the inner ring and the outer side by means of a cage, and its appearance, size, and total number immediately endanger the application and lifespan of the stamping bearing。

The holder can make the stamping die body evenly spread, prevent the specific fall of the stamping die, and correctly guide the specific rotation of the stamping die to achieve a smooth and practical effect. Double row radial curved surface ball bearings and double row radial spherical roller bearings have good cardiac function. Roller bearings and cylindrical roller bearings do not agree that the inner and outer centerlines have a relative inclination.

The agreed inclination angles for various stamped bearings are different, such as 8 '- 16' for single row radial ball bearings, 2 ° - 3 ° for double row radial curved ball bearings, and ≤ 2 'for deep groove ball bearings. Compared to rolling bearings, stamped bearings have a large axial limit, which allows them to absorb less vibration. At high speeds, they have a low life limit and a loud noise. When the axis of the bearing hole with seat is tilted, the rolling bearing can still work normally.
