Selection method of bearings
The demand for various mechanical equipment, instruments, etc. using rolling bearings in shopping malls is becoming increasingly stringent, and the conditions and functions required for bearings are also becoming more diverse. In order to select the most suitable bearing from numerous structures and scales, it is necessary to discuss from various perspectives. When selecting bearings, it is common to consider the difficulty of arranging, installing, and disassembling bearings as a shaft system, the space and scale allowed by the bearings, and the commercial nature of the bearings, in order to roughly determine the bearing structure. Secondly, while comparing and discussing the planned lifespan of various machinery using bearings and the different durability limits of bearings, the bearing scale is determined. When selecting bearings, it is often biased to only consider the fatigue life of the bearings, and it is necessary to fully discuss the grease life, wear, noise, and other issues caused by grease aging. Furthermore, based on different uses, it is necessary to select bearings that require special planning for precision, clearance, adherence to structural design, lubricating grease, and other requirements. However, there is no specific order or rule when selecting bearings. Priority should be given to the conditions, functions, and most relevant matters requested by the bearings, which is particularly practical.
Precautions for the use of bearings
Rolling bearings are fine components, and their application must also be carried out steadily accordingly. No matter how highly functional bearings are used, if not used properly, they will not achieve the expected high functionality.
The following are the precautions for the use of bearings.

(1) Persist in cleaning the bearings and their surroundings.
Even small dust that cannot be seen with both eyes can have a negative impact on the bearings. So, it is necessary to insist on cleaning the surroundings to prevent dust from entering the bearings.
(2) Use carefully.
Intense impact on bearings during use can cause scratches and indentations, which can become a contributing factor to the problem. In severe situations, cracks and fractures may occur, so it is necessary to pay attention.
(3) Use appropriate operational skills.
It is necessary to use appropriate things to prevent substitution with existing ones.
(4) Pay attention to the rust of the bearings.
When operating bearings, sweat on the hands can become a factor in rusting. Pay attention to operating with clean hands, and it is best to wear gloves as much as possible.
