How to prevent needle roller bearings rust

Needle roller Slewing bearing rust prevention methods
1, soak method: some small rust NSK Bearings by immersion in oils, oil film thickness can be controlled by anti-rust oil temperature or viscosity to achieve. Adhesion to the surface layer of rust grease approach.
2, brushing method: Brush evenly spread in the attention NSK bearing surfaces, do not produce accumulation and pay attention coated to prevent leakage.

3, the spray method: Some material not suitable for large-scale anti-rust oil coating by 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. This method must be improved fire protection and labor protection measures
