On this basis, the immersion method can be used to prevent rust, that is, the drawn cup needle roller bearing is directly immersed in the anti-rust grease, and the China Clutch Release Bearings surface is adhered with a layer of anti-rust grease. It is necessary to choose an appropriate method for cleaning according to the nature of the rust-proof object and the prevailing conditions.

Of course, it is also related to the surface finish of the drawn cup needle roller bearings. The method to avoid rust caused by hand sweat is that the production personnel should wear gloves, finger cots, or use special tools to pick up the bearing when installing the drawn cup needle roller bearing. The corrosion resistance. Generally, the oxygen concentration is poor and the battery is corroded. The sweat film will cause electrochemical effects on the bearing, corrode the bearing, and produce embroidery.

However, human sweat is inevitable. The corrosion of drawn cup needle roller bearings is due to its own materials, because it is made of bearing steel, so its chemical composition and structure may be oxidized by air to become embroidered. Do not use it at will Hand touch the bearing surface. In addition, the composition and pH value of the solution that touches the surface of the drawn cup needle roller bearing; the temperature and humidity of the environment where the bearing is stored; various environmental media that touch the surface of the bearing will also directly affect the drawn cup needle roller bearing. In order to prevent rusting of drawn cup needle roller bearings, the first thing to pay attention to is to clean the surface of the bearing.

Due to the influence of various connotations and external elements, drawn cup needle roller bearings may show corrosion, so before adopting anti-rust methods, it is necessary to fully understand the specific causes of the problem. The thickness of the oil film can be controlled to prevent The temperature or viscosity of the rust grease is reached. When sweat touches the bearing surface, it will form a layer of sweat film on the bearing surface. Then we can select useful solutions in a targeted manner.

In addition, human hand sweat can cause corrosion of the needle roller bearings in the stamped outer ring, because human sweat is a colorless, transparent or light yellow liquid with a salty taste and weak acidity. Generally, solvent cleaning is more common, chemical treatment cleaning method and mechanical cleaning method. The exterior of the drawn cup needle roller bearing can be dried with filtered dry compressed air after being cleaned and cleaned, perhaps with a drier at 120-170 degrees Celsius, or with clean gauze. In addition to containing sodium, potassium, calcium, and magnesium In addition to salt, it also contains a few organic acids such as urea, lactic acid, and citric acid
