The market requirements for various mechanical devices and instruments using high-temperature bearings are increasingly strict, and the conditions and performance required for bearings are also increasingly diversified. In order to select the most suitable bearing from a large number of structures and sizes, it needs to be studied from various angles.
When selecting bearings, the bearing structure is generally determined by considering the bearing arrangement, the ease of installation and disassembly, the space and size allowed by the bearing, and the marketability of the bearing.
The bearing size is determined by comparing and studying the design life of various machines using bearings and various durability limits of bearings. When selecting bearings, it is often biased to consider only the fatigue life of bearings. The grease life, wear and noise caused by grease aging also need to be fully studied.
According to different applications, it is necessary to select bearings with special design requirements for precision, clearance, cage structure, grease, etc. However, there is no certain order and rules for selecting bearings. The priority should be given to the conditions, performance and most relevant matters required for bearings, which is particularly practical.
