The market performance 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 diversified. In order to select the most suitable bearing from numerous structures and sizes, it is necessary to study from various angles.
When selecting bearings, generally, the bearing arrangement, ease of installation and disassembly of the shaft system, the space and size allowed by the bearing, and the marketability of the bearing are generally considered to roughly determine the bearing structure.
Next, determine the bearing size while comparing and studying the design life of various machines using the bearing and the various endurance limits of the bearing. When selecting bearings, it is often preferred to only consider the fatigue life of the bearing. The grease life, wear, noise, etc. caused by grease aging also need to be fully studied.
Furthermore, according to different uses, it is necessary to select specially designed bearings that meet requirements for accuracy, clearance, cage structure, grease, etc. However, there is no certain sequence or rules for selecting bearings. What should be considered first is the conditions, performance, and most relevant matters required for the bearings, which is especially practical.
