Vertical motor itself is only set on the guide bearing, the motor assembly is connected to two-way thrust bearing, two-way thrust bearings inside the motor - guide bearing is installed from the bottom, as in the gap between the common guide bearings and shaft mounting shoe It can not be adjusted, so the motor assembly stator and rotor concentricity demanding.

According to the technical requirements, install two-way thrust - guide bearing rotor disk during car at the shaft extension with respect to the two-way thrust bearing to the bottom surface of the aperture stop runout allowed a maximum of 0.03mm. If the shaft extension at the runout is too large, it will affect the follow-up process of the rotor vertical, which causes the shaft during normal operation the problem of excessive vibration motor, easy to wear shoe guide bearing.

Motor externally mounted on the reduction cylinder itself is only a guide bearings, thrust bearings, when assembling the motor in order to successfully plate car plate car must use tool.

Only a guide bearing for the motor, the motor type test no thrust bearing this characteristic design with a thrust bearing support, not only to solve the problem rotor support, but also solve the problem of disk drive. A long screw fixed on the rotor shaft, the shaft is provided with a thrust bearing to support the entire rotor, attached to the end of the screw rod used to rotate two crank rotor plate car work.
