The primary factors affecting bearing performance relate to whether installation adjustments, operational maintenance, and repair procedures comply with technical specifications. In accordance with the technical requirements for installing, operating, maintaining, and servicing deep groove ball bearings, the loads, rotational speeds, operating temperatures, vibration levels, noise emissions, and lubrication conditions of bearings in operation must be monitored and inspected. Any anomalies detected must be promptly investigated, rectified, and restored to normal operation.

The performance of deep groove ball bearing seal materials is paramount for ensuring effective sealing. Seal material selection primarily depends on the operating conditions of the sealing elements, including operating temperature, pressure, working medium, and motion patterns. Fundamental requirements for seal materials are as follows:

1.  Wear resistance without corroding metals;

2.  Good oxygen resistance and ageing resistance for long-term durability;

3. Resistance to both high and low temperatures, without decomposition or softening at elevated temperatures, nor hardening at low temperatures;

4. Compatibility with the operating medium, without swelling, decomposition, or hardening;

5. Appropriate elasticity and hardness, with minimal permanent deformation under compression. The metallurgical quality of bearing materials has historically been a primary factor contributing to premature failure in deep groove ball bearings. With advances in metallurgical techniques (such as vacuum degassing of bearing steel), raw material quality has improved. The proportion of raw material quality factors in bearing failure analysis has significantly decreased, yet it remains one of the primary influencing factors. Appropriate material selection remains an essential consideration in bearing failure analysis.
