What is the main cause of rolling bearing corrosion?
1. Rust reason: 1. Humidity Humidity in the air has a great influence on the corrosion rate of bearings. At critical humidity, the corrosion rate of metals is very slow. Once the humidity exceeds the critical humidity, the speed of metal corrosion will suddenly increase. The critical humidity of steel is about 65%. Due to the poor air mobility in the bearing production workshop
