The current our country science and technology and the development of various industrial departments, more and more long life, high precision are put forward for rolling bearing; Low noise, low vibration, high speed, overload, high rigidity and high reliability requirements. On the other hand, to meet the above requirement for bearing, bearing users must also be strictly in accordance with relevant provisions of all bearing application technology, to satisfy all the requirements for bearing application technology, the rolling bearing can be obtained when necessary professional department to cooperate, but only rely on to buy bearing high specification without application technology, tend to no avail.
Approaches to realize long life of rolling bearing, in principle can be due to the following points,
(1) to eliminate may cause bearing abnormal failure factors, the failure of the bearing can only be normal fatigue failure or wear failure;
(2) to improve the bearing fatigue life and wear life, prolong its life.
