SKF bearing products corrosion reason - bearing knowledge

The main reasons of corrosion are the following: 1, some enterprises in the process of production of SKF bearing no cleaning rust in strict accordance with the procedures and oil seal rustproof packaging requirements of SKF bearing parts in the process of machining and assembly after antirust processing SKF bearing products. Such as ring in the process of turnover turnover time is too long, outer cylindrical contact corrosive liquids or gases, etc. 2, some enterprises in the production of antirust oil, cleaning products such as kerosene used quality can not reach the requirements of the technology. 3, due to a SKF bearing steel price drop down again, resulting in SKF bearing steel quality decline gradually. Such as non-metallic impurities content in steel on the high side, The increase of sulfur content in the steel material fall in corrosion resistance) , metallurgical structure deviation, etc. Presently used source of SKF bearing steel production enterprises more miscellaneous, steel quality ichthyosaurs fraud. 4, part of the enterprise's poor environmental conditions, harmful content is high in the air, flow field is too small, it is difficult to effectively antirust processing. Coupled with the hot weather, the production workers in violation of the phenomenon such as antirust procedures were there. 5, some enterprises anti-rust paper, nylon paper ( Bag) And SKF bearing packing material such as plastic tube is not accord with the requirement of rolling SKF bearing oil seal rustproof packaging is one of corrosion factors. 6, some enterprises SKF bearing ring of turning small allowance and allowance of grinding, the oxide coating on the cylindrical, failed to completely remove decarburization layer is also one of the reasons.
