Understand Vertical Motor Bearings - Efficient Plant

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.
