Vertical motors are classified as normal thrust, inline 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 ...

Thrust bearings are rotary bearings that are designed specifically to support an axial load. In other words, they are capable of rotating along with a machine's parts. Thrust bearings, in fact, assist in the rotation of a machine's moving parts. As a machine's moving parts begin to rotate, they'll glide along the thrust bearings.

Four, five, or six recesses are typical, recess depth typically being 20 times the gap at the bearing lands. Each recess is controlled by its own restrictor so that each recess with its surrounding land acts as a thrust pad; a whole bearing consists of n pads, of which n/2 pads support vertical loads and n/2 pads support horizontal loads.
