TILTING PAD BEARINGS
The Ultimate Solution for High-Speed and High-Load Stability
Why Tilting Pad Bearings (TPBs)?
Tilting Pad Bearings (TPBs) represent the pinnacle of hydrodynamic bearing technology, engineered specifically to overcome the inherent limitations of traditional plain bearings, especially in high-speed and high-load turbomachinery. When your machinery operates at critical speeds and demands maximum stability, zero subsynchronous vibration, and minimal power loss, TPBs are the superior choice.
TPBs are designed to eliminate the risk of oil whip or oil whirl, a common instability in fixed-geometry bearings that can lead to catastrophic failure.
​
How They Work: The Hydrodynamic Wedge
Unlike plain bearings with a fixed lubricating film, a Tilting Pad Bearing is constructed from multiple (typically 4 to 8) individual pads arranged circumferentially around the shaft. The key principle is:
-
Independent Pad Movement: Each pad is free to pivot or "tilt" on a central or offset pivot point.
-
Self-Generating Wedge: As the shaft rotates, it drags the lubricating oil (or fluid) into the converging gap between the shaft and the leading edge of the pad. This tilting motion automatically forms a highly stable, self-adjusting hydrodynamic wedge of lubricant under each pad.
-
Dynamic Stiffness and Damping: This fluid wedge provides powerful dynamic stiffness and damping that actively stabilizes the rotor, effectively suppressing undesirable vibrations and rotor instabilities over a wide range of operating speeds.
