The use of various mechanical devices, apparatus, etc. Rolling increasingly stringent market requirements for performance, the conditions required by the bearing performance is becoming increasingly diverse. In order from a large number of structu re, size, and select the most suitable bearing, you need to study from various angles. In the choice of bearings generally consider as the shaft bearing arrangement, installation, ease of disassembly of the space allowed by the bearing size and bearing market, etc., generally determine the bearing structure. Second, while Comparative Study of the various mechanical design life and bearing using the bearing a variety of durable limits, while the bearing size. Often biased in the choice of bearing only to consider the bearing fatigue life, grease life of aging by the grease, abrasion, noise need to fully research. Furthermore, according to different purposes, it is necessary accuracy, clearance, and maintain the requirements of the aircraft structure, grease, etc., for a specially designed bearing. Select bearings, however, there is no certain order, rule, priority consideration should be given the required conditions on bearing performance, the most related matters, particula rly practical.ball bearing
