Summary of bearing selection:
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 be able to select the most suitable bearing from among a large number of structures and sizes, it is necessary to study from various angles. When selecting a bearing, generally considering the bearing arrangement as a shaft system, the ease of mounting and dismounting, the space allowed for the bearing, the size, and the marketability of the bearing, the bearing structure is roughly determined. Secondly, the bearing dimensions are determined while comparing the design life of various machines using bearings and the various endurance limits of the bearings. When selecting a bearing, it is often preferred to consider only the fatigue life of the bearing. The grease life, wear, noise, etc., which occur due to aging of the grease, also need to be fully studied. Furthermore, depending on the application, it is necessary to select a bearing that is specially designed for accuracy, clearance, cage structure, grease, and the like. However, there is no order or rule for selecting bearings. It is especially practical to consider the conditions, performance, and most relevant requirements for the bearings.
