Function of bearing: Bearings one part of the role is support, its essence is the ability to bear the radial load. In another word: it controls axial and radial movement. Without bearing the consequences of motor is simply not work. Because the shaft may move in any direction, the electrical work required to rotate shaft only. Theoretically speaking, the role of transmission can not be achieved, whats more, bearing also affect the transmission, in order to reduce this impact, bearing lubrication must be to achieve good in high-speed shaft. While most of the bearings must have a lubricating oil which responsible for high-speed operation. As the friction will not only increase energy consumption, even more frightening is very easy to damage bearings. The sliding friction into rolling friction of the argument is one-sided, because a kind of sliding bearing is called.
