Rolling bearings often work under high-speed and heavy-load conditions. After long-term use, the rolling elements and raceways will experience wear, ablation, cracking, fatigue spalling, and spots. The inspection of rolling bearings is generally not disassembled. It should be cleaned during inspection, and the quality can be judged through external inspection, idling inspection and internal clearance inspection.

When selecting bearings, generally consider the bearing arrangement as the shafting, the ease of installation and disassembly, the space allowed by the bearing, the size and the marketability of the bearing, etc., which roughly determine the bearing structure. Next, determine the bearing size while comparing and studying the design life of various machines using bearings and the various durability limits of bearings.

Furthermore, according to different uses, it is necessary to select bearings specially designed for the requirements of precision, clearance, cage structure, grease, etc. However, there is no certain order and rules for selecting bearings. The priority should be the conditions, performance, and most relevant options required for the bearings, especially practical.
