          Rust Factors and Anti-rust Measures for Stamping Needle Roller Bearings with Outer Ring

          Due to the influence of various internal and external factors, the exterior ring needle roller bearings may be corroded, so before taking anti-rust measures, we should fully understand the specific causes of the problem. Then we can adopt effective solutions.

          The corrosion of stamping needle roller bearing has its own material reasons. Because it is made of bearing steel, its chemical composition and structure may be oxidized into embroidery by air. Of course, it is also related to the surface smoothness of needle roller bearings with stamping outer rings. Generally, the oxygen concentration difference battery is corroded.

          In addition, the solution composition and pH value contacted with the surface of punched outer ring needle roller bearing, the environmental temperature and humidity stored in the bearing, and various environmental media contacted with the bearing surface will also directly affect the corrosion resistance of punched outer ring needle roller bearing.

          In order to prevent rust of needle roller bearings with stamped outer rings, first of all, attention should be paid to the cleaning of the bearing surface. The proper cleaning method must be selected according to the nature of the surface of the rust-proof material and the conditions at that time. Generally, solvent cleaning is more common, chemical treatment cleaning method and mechanical cleaning method.

          After the surface of the needle roller bearing is dried and cleaned, it can be dried by filtered dry compressed air, or by a dryer of 120-170 degrees Celsius, or by a clean gauze. On this basis, we can use the immersion method to prevent rust, that is, the pressing needle roller bearing is directly immersed in the rust-proof grease, so that its surface is adhered to a layer of rust-proof grease. The thickness of the oil film can be achieved by controlling the temperature or viscosity of the rust-proof grease.

          There is also the human hand sweat can cause the rust of needle roller bearing stamping outer ring, because human sweat is a colorless transparent or pale yellow liquid with salty taste and weak acidity, in addition to containing sodium, potassium, calcium, magnesium salts, but also contains a small amount of urea, lactic acid, citric acid and other organic acids. When the sweat contacts with the bearing surface, a layer of sweat film will be formed on the bearing surface. The sweat film will cause electrochemical action on the bearing, corrode the bearing and produce embroidery.

          But sweating is inevitable. The way to prevent hand sweat from causing rust is to wear gloves, fingerprints or special tools when assembling stamping needle roller bearings, and not touch the bearing surface with hands.
