Tilting Pad Bearings

Tilting-pad bearings deliver many advantages including:
Improved dynamic performance of the rotor-bearing system and drastic reduction of instability caused by lubricating oil
Bearing adaptability to shaft movements as a result of the ability of the shoe to tilt
Uniformly distributed oil flow from equidistant radial feed holes
Increased stability due to greater damping
Lower spare parts costs and faster delivery since only the pads need to be changed
In turbo machinery operating at high speeds, plain cylindrical bearings are susceptible to oil film instability. In this condition, also known as oil whirl, the shaft orbits within the clearance of the bearing. The tilting pad journal bearing uses tilting pads to provide geometries that change with variations in load or speed. This bearing offers the best stability at all conditions.
