The shingle is actually a scraped surface, usually the inner surface of the hole, the purpose of which is to improve the contact condition, to generate the small concave point and to improve the lubrication. Scraping the requirements of the bearing should be treated according to the practical situation

The damage in the use of the gasoline engine bearing is mainly wear, fatigue, peeling and ablation. The surface cleanliness of the parts is poor.Low machining accuracy, maintenance and improper use (FIG. 2 shows the damage to the axial alloy).

In recent years, the number of car owners has gradually increased, and the car needs regular maintenance, but some of the limited maintenance centers often go into maintenance mistakes and affect the performance of the vehicles. There are 10 main performances:
