Bearing Technology

Bently Nevada Corporationuid Control Bearing operates by delivering pressurized fluid through recessed inlet ports. Each port directs fluid to a bearing pocket. Fluid flow through the bearing is restricted by each inlet port and also by the journal/bearing clearance. As the rotor attempts to move in the bearing, pocket pressure increases in the direction of motion and decreases in the direction opposite motion, creating a pressure differential in opposing bearing pockets and a corresponding restoring force to the rotor. By properly designing and pressurizing a bearing, it can be made stable for all operating speeds of interest. If high-pressure supply fluid is lost, the bearing simply reverts to operation as a conventional hydrodynamic bearing, allowing the machine to be shut down safely. Additional features include:

•Exceptional stability, stiffness, heat removal and efficiency
•Independently adjustable stiffness and damping
•Flexible working fluid choices
•Excellent rotor/bearing/seal life
