Design Notes:


The following guidelines for assigning load capacities to tilt-pad fluid film thrust bearings take into consideration theoretical analyses, field experience, and actual test results.

  • Load capacity is based on film thickness and white metal temperature
  • Larger thrust bearings for low or moderate speed applications are rated for higher specific loads (load per unit of area) than smaller thrust bearings
  • Frictional power loss increases with higher rotational speed, greater oil viscosity, and larger thrust bearings
