Bearing selection methods


The market requirements for various mechanical devices and instruments using rolling bearings are becoming increasingly stringent, and the conditions and performance required for bearings are becoming increasingly diverse. In order to select the most suitable bearing from a large number of structures and sizes, it is necessary to study them from various angles. When choosing a bearing, generally, consider the arrangement of the bearing as a shaft system, the ease of installation and dismantling, the space allowed for the bearing, the size and the marketability of the bearing, and so on, to determine the bearing structure in general. Secondly, while comparing the design life of various machinery using bearings and the various durability limits of bearings, while deciding on the bearing size. In the selection of bearings, often biased to only consider the fatigue life of the bearing, about by the grease aging and grease life, wear, noise, etc. also need to be fully studied. Furthermore, according to the different uses, it is necessary to choose the bearings with special design for accuracy, clearance, cage structure, grease and other requirements. However, there is no certain order, rules, priority should be given to the bearing requirements of the conditions, performance, the most relevant matters, especially practical.
