Will frequent starting and stopping of the motor affect the motor bearings?

The primary roles of bearings include supporting the mechanical rotating body, reducing the coefficient of friction in motion, and ensuring the accuracy of its rotation. Obviously, motor bearings hold the motor shaft in place while regulating the axial and radial position and movement of the rotor to produce circumferential rotation. So what does the frequent starting and stopping of the motor have to do with the motor bearings? Let's take a look at the following

Due to the frequent starting and stopping of the motor and the back and forth rotation, there are some special requirements for the motor winding, shaft extension and the fixation between the components. These requirements include the insulation level of the motor winding, the shaft extension is more conical, the stator core and seat, the rotor core and shaft are fixed by long key positioning, etc. 

The motor often rotates in both directions, and the bearings affect this situation. Deep groove ball bearings and cylindrical roller bearings are used more in small and medium-sized motors. These bearings are symmetrical structure, there is no provision for steering the bearings, and there is no restriction on the assembly direction, so forward and reverse rotation will not affect them. The quality of the corresponding parts of the bearing is directly related to the normal operation of the bearing, as the motor often rotates forward and backward, resulting in the offset of the motor shaft and thus the inconsistent center of the bearing system.
