Operation and Maintenance of Vertical Motors | Pumps & Systems

17/12/2011· Angular contact ball bearings are the most common thrust bearings in vertical motors. A single bearing is used for normal thrust loads. Two bearings can be used in tandem for 175 percent of normal thrust (see Figure 2), and three bearings can be stacked for 250 percent of normal thrust. Stacks of up to five bearings have been reported.

Electric motor bearings and their appliion

Electric motor bearings. The purpose of a bearing in an electric motor is to support and loe the rotor, to keep the air gap small and consistent and transfer the loads from the shaft to the motor. The bearings should be able to operate at low and high speeds whilst minimizing frictional loses. At the same time the bearing must be economic
