Bearings ("Bearing", the Japanese called "axis by") is fixed and reduce the load coefficient of friction components in mechanical transmission process. You can also say that when the other parts on the shaft movement relative to each other, the process used to reduce the power transmission coefficient of friction and keep the shaft center position fixed parts. Bearing is a kind of modern machinery and equipment vital components. Its main function is to support the mechanical rotary member, the drive device for reducing the mechanical load during the friction coefficient. According to the different nature of friction of moving parts, the bearings can be divided into two types of rolling bearings and plain bearings.
