Nidec Motors - Vertical Thrust Radial Designs

In vertical motors thrust is an unusually heavy weight or load applied in one or both directions. Thrust is the most important consideration to high, medium and low thrust turbines or centrifugal pumps. This is the value of the impeller (K Factor) plus shaft and hydraulic weight. For instance, for every foot of water, there is a certain amount

Thrust Bearings to Reduce Friction and Support Axial Loads

Thrust bearings include a variety of bearings that assists axial loads or axial force . It is an axial bearing that permits rotation between parts. Thrust bearings support the axial thrust of both horizontal and vertical shafts. The functions are to prevent the shaft from drifting in the axial direction and to transfer thrust loads applied on

Understand Vertical Motor Bearings - Efficient Plant

11/4/2018· Vertical motors are classified as normal thrust, in-line thrust, or high thrust. Normal thrust loads can be determined from tables based on the motor’s speed and horsepower rating. High thrust is a multiple of normal thrust, such as 175%, 250%, and 300%. We will see, later in this article, how bearings are arranged to accommodate each of
