Understand Vertical Motor Bearings - Efficient Plant

Apr 11, 2018· A hydrodynamic bearing, also known as a tilting-pad, plate, or Kingsbury bearing (Fig. 5), is capable of extremely high thrust loads and very long life. As with sleeve bearings in horizontal motors, there is theoretically no wear on the plates because the load is carried on an oil film that separates the moving parts.

The pads, however, do not allow any axial tilting motion, and can lead to high pivot stresses if there is any misalignment. The full surface contact of the spherical ball and socket pivot reduces stress on the pivot compared to the rocker back design, and also allows tilting in all directions. Bearings Plus can further optimize tilt pad journal ...
