Cross roller bearing surface rust work

Cross roller bearings in the preservation and operation of the process, because of its metal and the external environment, it is easy to produce rust. This not only greatly affect the running properties of the bearing, reduced efficiency. But also to the bearing life greatly reduced. cross roller bearing rust of the surface pretreatment methods:

1 Surface cleaning: cleaning rust must be in accordance with the nature of the surface and the prevailing conditions, select the appropriate method. Commonly used with solvent cleaning, chemical cleaning and mechanical cleaning treatment method.

2 available after the surface is dry clean filtered thrust cylindrical roller bearings drying compressed air, or by 120 ~ 170 ℃ of the drier, can also be wiped clean gauze.

Coated with anti-rust oil Method:

1 immersion method: Some small items using immersion in rust oils, allowed a layer of rust on the surface adhesion grease approach. Antirust film thickness can be controlled by the temperature or viscosity of the oil to achieve.

2 brushing method for NA immersion or spray outdoor construction equipment or special shape products, brush when it is necessary to pay attention not produce accumulation and pay attention coated to prevent leakage.

3 spray some large objects can rust oiled using immersion method, generally about 0.7Mpa pressure filter with compressed air spray cleaner place. Spray application of anti-rust oil or solvent dilution thin rust oil, but must adopt comprehensive fire protection and labor protection measures.
