Thin section crossed roller bearings rust causes and preventive measures
Thin section crossed roller bearing corrosion, there are two main reasons: First, the bearing itself metal corrosion, corrosion of two human factors.
Bearing itself accounted for the vast proportion of metal corrosion, because the work needs, many times this is unavoidable. Human contact bearing, the hand can cause bearing corrosion sweat, sweat contact bearings mainly in its surface sweat membrane interactions lead to corrosion electrochemical reaction will occur, but this is to be avoided, such as to bring professional pick Part of gloves and other tools.
Thin section crossed roller bearings cause metal corrosion which is mainly reflected in the following points:
1, the surface finish;
2, the metal materials, chemical structure and composition;
3, the metal surface of the component and the PH value of the solution;
4, the environmental media;
5, the ambient humidity and temperature.
Thin section cross roller bearing prevent corrosion measures are mainly: to maintain the bearing surfaces are clean, and the cleaning must use the appropriate method. General chemical treatment cleaning, mechanical cleaning and a solvent cleaning methods. Clean the surface after drying compressed air available, you can also use 120 ~ 170 ℃ the drier, and then wipe dry with a clean gauze. Finally, the bearings coated with anti-rust oil, as follows:
Using the immersion method, the film thickness can be controlled by anti-rust oil temperature or viscosity to achieve. Some small items using immersion in rust oils, allowed surface adhesion layer of anti-rust oil; Dena Man Mr. Gao
Using a spray method, the object can not be taken to some large rust oiled soaking method for thin-layer anti-rust oil or solvent dilution type rust preventive oil, but pay attention to labor and fire protection measures;
Use brushing, brushing not only to avoid the accumulation does not produce, but also to prevent leakage caused by paint. For non-immersion or spray with some of the special shape of the products or outdoor construction equipment.
