The basic concept of bearing life -

According to the latest rolling bearing fatigue life theory, an excellent design, excellent material, excellent manufacture and install the correct bearing, as long as enough to easily subjected to the load ( No greater than the corresponding a durability limit load bearing value) , the bearing will never produce fatigue damage of materials. The bearing will run indefinitely. The significance of this theory is that it not only provides a more than the ISO equation is more reliable to predict the tools of modern bearing life, and is that it shows all the fatigue life of rolling bearing has a considerable development potential, and shows the ways to develop the potential, thus to bearing product development, quality management and application of technology has a profound impact. Bearing, however, is only possible in the laboratory under the condition of infinite 'implementation', and this kind of condition for bearing under certain condition of field use, both difficult to is too expensive. Field use bearing, the work load is often greater than its corresponding fatigue durability limit load, after the work to a certain time limit, or late or early due to the material itself will always reach contact fatigue limit and fatigue spalling and cannot continue to use. Even if some bearing working load is lower than its corresponding durability limit load, also due to the bearing the problem of pollution of hard to eradicate the wear failure occurred. To sum up, the scene of bearing more or less in use can't fully meet those of the lab conditions, and slightly in either condition, will reduce bearing period are available, and this leads to the life of the bearing problem. Generally speaking, the service life of rolling bearing is refers to the rolling bearing in the actual service conditions ( Including working conditions, environmental conditions and maintenance and maintenance, etc. ) Satisfy the requirement of active, can continue to keep working performance and precision of the specialty service period. Bearing on production of 2 mm diameter 30 ~ 40 mm 30 small small-sized bearing, has high precision, small vibration, low noise, high performance, high speed, long life and other excellent features. Widely used in household appliances, electric tools, small-sized electric machinery, fitness equipment, office automation equipment, medical equipment, instrumentation, internal combustion engines, construction machinery, railway vehicle, loading and unloading handling machinery, agricultural machinery, all kinds of industrial machinery, etc. Buy miniature bearings, motor bearings, deep groove ball bearing, please find bearing.
