Investigate its role should be to support

Investigate its role should be to support, that the literal interpretation is used to bearing axis, but this is only part of its role in supporting its essence is to be able to bear the radial load. Also it can be understood as it is used to a fixed axis.slim section ball bearing Bearing quick and easy selection of excellent automation have included. It is fixed shaft it can only achieve rotation, and control of its axial and radial. Motor without bearing the words simply do not work. Because the axis may be in any direction movement, the motor work requirements shaft can only be rotated. In theory, the role of transmission can not be achieved, not only that, bearing also affect the transmission, in order to reduce the impact on the high speed shaft bearings must achieve good lubrication, lubrication some bearing itself, called pre-lubricated bearings, and most of the bearing lubricant, responsible for high-speed operation, due to the friction will not only increase energy consumption, even worse, it is very easy to damage the bearings. The sliding friction into rolling friction is one-sided, because the kind called plain ball bearing thing.
