Rolling bearing corrosion causes and prevention methods of rolling thin wall bearing corrosion is caused by a variety of internal and external factors, sum up the main are: 1, metal surface finish,
The oxygen concentration cell corrosion)
。
2, contact with the metal surface composition and pH value of solution;
3, metal material chemical composition and the structure itself.
4, with various environmental medium metal surface in contact.
5, the other people's sweat is the cause of corrosion caused by angular contact ball bearing, its pH value of 5 ~ 6.
So in order to prevent hand sweat cause corrosion, installation and production personnel should wear gloves, don't contact with the hand rolling bearing.
6, environmental temperature and humidity.
Rolling bearing corrosion causes and prevention methods of 1, brush, brush the note smear evenly on the surface of the rolling bearing, don't build up, also should pay attention to prevent leakage.
2, soaking method: some small rolling bearing by soaking in antirust oil, oil film thickness can be controlled by the antirust oil temperature or viscosity to achieve.
Make a layer of anti-rust oil on its surface adhesion method.
3, spray method: some big rust is not suitable for oil by soaking method, generally about 0.
7 mpa pressure filtering compressed air spraying where clean air.
Spray method used solvent XiShiXing rust-proof oil or thin layer of anti-rust oil.
This method must be used to perfect fire prevention and labor protection.
A: on the precision of the rolling bearing and rank next: needle roller bearing is there without a cage type
