2.1 Bearing materials and manufacturing processes

The selection of bearing materials and manufacturing process directly affect the life of the bearing. Advanced material technology and optimized manufacturing processes can improve the wear resistance and fatigue resistance of bearings, thereby extending their life.

2.2 Lubrication and sealing

Good lubrication and sealing play a key role in bearing life. Proper lubrication reduces friction and wear, while effective sealing prevents external contaminants from entering the bearing and protects it from damage.

2.3 Load and speed

Bearings work under different loads and speeds, which have a direct impact on their lifespan. Reasonable load and speed matching can reduce bearing fatigue and extend service life.

2.4 Temperature and vibration

Excessive temperatures and large vibrations can lead to premature bearing failure. Therefore, effective temperature control and vibration monitoring are important means to improve bearing life.

Bearing life is a comprehensive performance indicator that is affected by many factors. Through in-depth research on bearing life, reasonable design and maintenance strategies can be formulated to improve the reliability and stability of mechanical systems. Future research directions can focus on new materials, new lubrication technologies, and intelligent monitoring systems to further improve bearing life and performance.
