The effect of bearing

The effect that should be supported, namely literal interpretation to the bearing, but this is only a part of its roles, supporting its essence is to bear radial load. Can also be understood as it is for a fixed shaft. Is the only fixed axial bearing rotation, moving to control the axial and radial. Motor without bearing the consequences that would not work at all. Because the shaft can move in any direction, and the motor work requirements can only rotate axis. Impossible to achieve the transmission function, speaking theoretically not only so, bearing will affect the transmission, in order to reduce deck crane bearing the influence to achieve good lubricating the bearings on the high speed shaft, the bearing itself has lubrication, called pre lubricated bearings, and most of the bearings must be responsible for lubricating oil, when running at high speed, because of friction will increase energy consumption, more terrible is easy to damage the bearing. The sliding friction into the rolling friction is one-sided, because there is something called sliding bearing.
