Oil Discharge Configurations in Fluid Film Bearings

Published on: 

We have conducted experimental tests on a variety of oil discharge configurations. The results? We have found that overall bearing power loss and performance are affected by:

  • Radial or tangential discharges
  • The clearance between the rotating thrust collar and the stationary housing, and
  • The diameter of the discharge port.

For high speed applications, our recommended discharge dimensions have been incorporated in a separate bearing accessory called an oil control ring. The oil control ring fits into the housing as a stationary shroud that provides proper clearance around the rotating thrust collar, and includes a properly sized tangential discharge opening. You can find bearing housing dimensions for oil control ring installation on the following pages.
