What are the accuracy grades and axial clearance standards of deep groove ball bearings?

The accuracy grade and axial clearance standards of deep groove ball bearings are usually defined according to international standards, and mainly include the following:

1. Accuracy level:

- ISO 492: The accuracy grade standard formulated by the International Organization for Standardization (ISO). The accuracy grade of deep groove ball bearings is divided into five levels: P0, P6, P5, P4 and P2. Among them, P0 is general accuracy and P6 is ordinary accuracy. P5 is high precision, P4 is ultra-high precision, and P2 is ultra-precision level.

2. Axial clearance standards:

- ISO 5753: This standard specifies the basic dimensions and clearances of deep groove ball bearings, including six grades: C0, CN, C2, C3, C4 and C5. Among them, C0 represents standard clearance, CN represents conventional clearance, C2 represents small clearance, C3 represents ordinary clearance, C4 represents large clearance, and C5 represents extra large clearance.

When selecting products, users should make reasonable choices based on the use requirements of the bearing, the working environment and the design requirements of the bearing itself.
