Kingsbury Inc. — Fluid Film Tilting-Pad Thrust & Journal Bearings
Authorized Supply Partner: PT. Atlas Prima Internasional (API)
Kingsbury Inc. (Philadelphia, PA, USA) is the pioneer and world authority in hydrodynamic tilting-pad thrust and journal bearings. Invented by Dr. Albert Kingsbury, these fluid film bearings eliminate metal-to-metal contact in high-speed, heavy-load rotating machinery — supporting steam and gas turbines, multi-stage boiler feed pumps, centrifugal compressors, hydroelectric generators, and marine propulsion shafts globally.
PT. Atlas Prima Internasional provides genuine Kingsbury bearing assemblies, replacement shoes/pads, RTD-embedded shoes, and certified rebabbitting services for Indonesian industrial operations.
