Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings generally consist of inner rings, outer rings, rolling elements and cages. For sealed bearings, plus lubricant and seals (or shields), this is the basic composition of the bearing.
Different bearings have different characteristics, and their characteristics are suitable for various application conditions of various mechanical equipment. To choose bearings suitable for different machinery from many varieties, we need to pay attention to two points:
1. It must be suitable for the use environment of the machine and the requirements for the bearing.
2. It is relatively easy to purchase replacement bearings, which is convenient for mechanical maintenance and inspection.
