1. Impact force and bearing damage
Frequent or high-speed through the pit, the impact force will be directly transferred to the bearing, may lead to bearing internal components (such as ball, cage) deformation, crack or spalling, accelerated wear
2. Influence of pitting texture
Positive effect: Research shows that reasonable design of pit texture on bearing surface (such as bearing area or lubricating oil supply area) can improve lubrication conditions, reduce friction coefficient, and extend bearing life
Negative risk: If the pit is located in a stress concentration area and is poorly designed (such as excessive edge treatment), it may weaken the bearing structural strength and increase the risk of damage
3. Key factors in actual use
Road conditions and driving habits: long-term driving on potholes will significantly shorten the bearing life, it is recommended to slow down and check regularly
Maintenance cycle: Ordinary vehicle wheel bearings are recommended to be checked every 50,000 kilometers and replaced about 100,000 kilometers, but the cycle needs to be shortened in bad road conditions
