Avoid needle bearing rust what method

In addition to use fixed number of year longer or needle roller bearing in the bad environment of rust, other condition usually appear rusty phenomenon. Needle roller bearings are generally do the antirust processing before they go out, today sure you introduce everyone to avoid needle bearing rust what method. 1, the first 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. 2, bearing surface dry cleaning: clean and dry compressed air filter available after dry, or in 120 ~ 170 degrees Celsius dryer for drying, also can use clean cloth to wipe dry. 3, soaking method: needle roller bearing by soaking in antirust oil, make its surface adhesion on a layer of anti-rust oil. The temperature of the oil film thickness can be controlled by anti-rust oil or viscosity to achieve. 4, and the hand of the sweat will cause the corrosion of needle roller bearing, people sweat is a colorless transparent or light yellow with salty in weak acid liquid, its pH value of 5 ~ 6. In addition to containing sodium, potassium, calcium, magnesium salt, also contains a small amount of urea, lactic acid, citric acid and other organic acids. 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. Sweating is inevitable, to prevent hand sweat cause corrosion method, is the production personnel should wear gloves when bearing assembly, refers to the set, or use the special tool take bearing, don't contact bearing surface by hand.
