The selection of the bearing

Using rolling bearing all kinds of machinery, instruments, such as market performance has become increasingly strict, for bearing the required conditions, the performance is also increasingly diverse. In order to from a large number of structure, size, choose the most suitable bearing, need study from various angles. When choosing bearing, generally, considered as a shafting bearing arrangement, installation, remove the difficulty level of, bearing, size allowed by the space and marketability of bearing, roughly defines the structure of the bearing. Secondly, comparative study on various mechanical design life of the bearing and the bearing of a variety of different endurance limit bearing has to be decided. When choosing bearing, tend to be only consider the fatigue life of bearing, the aging by grease and grease, wear life, noise, etc. Also need to be fully research. Furthermore, according to different purposes, it is necessary to select precision, clearance, cage structure, grease, etc. , as a special design of the bearing. However, choosing bearing no certain order, rules, consideration should be given priority is to bearing the required conditions, performance, most related matters, especially the actual.
