Factors of stamping outer ring needle roller bearing rust and antirust

Bearing manufacturing co. , LTD. Jiaxing stamping outer ring needle roller bearing has its material corrosion reasons, because it was made of bearing steel, so its chemical composition and structure has the potential of oxidation by air to embroider. And stamping outer ring needle roller bearing surface finish, of course, also have relations, general difference of oxygen concentration cell corrosion. In addition, with the stamping outer ring needle roller bearing surface contact solution composition and pH value; For bearing the environment temperature and humidity; The various environmental medium such as bearing surface in contact with will directly affect the stamping outer ring needle roller bearing corrosion resistance. For stamping outer ring needle roller bearing rust, first pay attention to the bearing surface cleaning, cleaning must be rust in accordance with the nature of the surface and the conditions, select the appropriate method. Is generally more solvent cleaning, chemical cleaning and mechanical cleaning method. Stamping outer ring needle roller bearing surface available filter after dry clean dry compressed air blow dry, or with a 120 - 170 degrees Celsius dryer for drying, also can use clean cloth to wipe dry. On this basis to rust by soaking method, is the stamping outer ring needle roller bearing directly soaked in antirust oil, make its surface adhesion on a layer of anti-rust oil, the method of oil film thickness can be controlled by the antirust oil temperature or viscosity to achieve. And the hand of the sweat will cause the corrosion of stamping outer ring needle roller bearing, because people's sweat is a colorless transparent or light yellow color with salty in weak acid liquid, in addition to containing sodium, potassium, calcium, magnesium salt, also contains a small amount of urea have ^ acid, citric acid, etc. When the sweat and the bearing surface contact, in the bearing surface to form a film of sweat, sweat membrane causes of bearing of electrochemical action, corrosion bearing, thus produce embroidery. But people sweating is inevitable, to prevent hand sweat cause corrosion method, is the production personnel in stamping outer ring needle roller bearing assembly should wear gloves, gloves, or use the special tool take bearing, don't contact bearing surface by hand.
