This is due to open in the bearing grease has been most
It is generally believed that sealed rolling bearing grease filling amount, shall not be more than about 50% of the internal space.6, some enterprises 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..Grease filling amounts to 60% of the SKF bearing internal space volume, the friction torque is no longer increased obviously.The main reasons of corrosion are the following:1, some enterprises in the process of production of bearing no rust cleaning procedures and oil seal antirust packing in strict accordance with the requirements of bearing parts in the process of machining and assembly after antirust processing of SKF Bearings catalog the more grease filling amount, the greater the friction torque will be.3, due to a bearing steel price drop down again, resulting in bearing steel quality decline gradually.The same filling amount, the sealed bearing friction torque is greater than the open bearing.
This is due to open in the bearing grease has been most extrusion, but also has lost in the sealed bearing grease.Shawki and Mokhtar test shows that the bidirectional thrust ball bearing, 20% to 30% in the most appropriate.Such as non-metallic impurities content in steel on the high side, the increase of sulfur content in steel making material itself corrosion resistance drops), metallurgical structure deviation, etc.
With the increased amount of grease filling, two-way thrust ball bearing linear temperature increase, the same filling amount, SKF bearing temperature rise is higher than the open bearings.com/ products.Is now used in bearing steel production enterprise source is miscellaneous, steel quality fish dragon fraud.Coupled with the hot weather, the production workers in violation of the phenomenon such as antirust procedures were there.2, some enterprises in the production of antirust oil, cleaning products such as kerosene used thrust bearings quality can not reach the requirements of the tilting pad bearing technology.Such as ring in the process of turnover turnover time is too long, outer cylindrical contact corrosive liquids or gases, etc.needle-roller-bearing.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.5, some enterprises anti-rust paper, nylon paper (bag) and a bearing packaging materials such as plastic cylinder does not accord with the requirement of rolling bearing oil seal rustproof packaging is one of corrosion factors
