Spherical Roller Bearings 2nd Generation Design Features Stamping Reinforced with Steel Stamping Reinforced symmetrical, roller optimized design with a much more traditional product Rated load Applications Wide range of service life. Second-generation design Another structural features Precision machining Brass reinforced reinforced symmetrical roller Rated load design The same design, the liquid dynamic and dynamic bearing Common axle housing Bearing Bearing type Seal type Precision bearings Inter-process rust-proof new technology Bearing life strengthening A detailed analysis of the test eccentric shaft parallel machine tool design theory and key technologies Non-oil bearing drive mold industry revolution China bearing life test to strengthen the ascendant
Spherical roller bearings traditional design, characterized by asymmetric roller, two copper cages. It can be replaced by the following various designs.
Spherical roller bearings second generation design, characterized by the use of steel stamping cage, reinforced symmetric roller, the optimal design, with much higher than the traditional products rated load, a wide range of applications, long service life.
Another design of the second generation of the structure, characterized by the use of precision machined brass cage, reinforced symmetric roller, rated load and c-type design of the same type can be used with the c-type design, especially the large size models.
The traditional structure of the improved design, with two precision machined brass cage, fixed on the inner ring wall, and the use of reinforced symmetric roller, the bearing load capacity to c-type design level, in the alternative to traditional products It is possible to have a longer life.
The bearings are designed with advanced Torrington technology and the latest third-generation products, the design parameters are fully optimized, the contact area has a more reasonable stress distribution, and the use of fine raw materials and sophisticated processing technology, which has a higher Carrying capacity and longer service life, reached the world advanced level.
According to the latest theory of rolling bearing fatigue life, a good design, material excellence, well-made and the correct installation of the bearing, as long as the bear the load easily enough (not more than the bearing corresponding to a persistent limit load value) The material will never produce fatigue damage. Therefore, as long as the bearing temperature and suitable for the work environment is not the magnitude of change, absolutely no solid dust, harmful gases and moisture intrusion bearings, bearing lubrication and adequate, the lubricant is absolutely pure without impurities, and will not deteriorate ... ... , Then the bearing will run indefinitely.
The significance of this theory lies not only in its ability to provide a more reliable predictor of modern bearing life than its life-form equation but also in showing that all rolling bearing fatigue life has considerable potential for development and demonstrates the potential to develop Of the way, thus bearing product development, quality management and application of technology has a profound impact.
The use of bearing its work load is often greater than its corresponding fatigue durability limit load, work to a certain period of time, or late or early will always be due to their own electrical fatigue limit material, resulting in fatigue and can not continue to use. Even if some of the bearing load is lower than its corresponding ultimate load, it will be difficult to eradicate the problem of bearing wear and tear caused by failure. In short, on-site use of the bearing more or less can not fully meet the above-mentioned laboratory with those conditions, and any conditions are slightly less, will shorten the useful life of the bearing, which resulted in bearing life problems.
In short, the life of rolling bearings is the rolling bearing in the actual service conditions (including working conditions, environmental conditions and maintenance and maintenance conditions, etc.), can continue to meet the active requirements of the work performance and working accuracy of service life.
