Bearing the choice of summary:
The rolling bearings of various mechanical devices, apparatus and other market requirements increasingly stringent performance, bearing the required conditions, the performance is also becoming more diverse. In order from a large number of structure, 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, demolition of the degree of difficulty, the bearings allow the space, size and bearing market price, and 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. It 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 maintains 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, particularly practical; consider bearing the Tesco extent and frequency.
