Reduce Power Loss, Extend Bearing Life
Flexure Pivot® tilt pad thrust bearings reduce power loss and extend bearing life over a wide range of speeds, loads and temperatures.
The Flexure Pivot tilt pad design forms a converging wedge through flexure of a post support, eliminating pivot wear and high contact stresses associated with point or line contact tilt pads.
The Flexure Pivot post support is customized for each application to provide an optimum wedge ratio at design load conditions, resulting in an increase in the load capacity and a significant reduction in horsepower loss.
Elimination of Pad Flutter
The rotational stiffness provided in the Flexure Pivot tilt pad bearing eliminates the pad flutter problem that can be experienced on the inactive side of standard tilt pad thrust bearings.
Easy Implementation of Hydrostatic Feature
Offset Flexure Pivot tilt pad thrust bearings can carry higher load capacities in reverse rotation than standard tilt pad bearings, giving them an additional benefit in certain high-load applications. The hydrostatic feature can be utilized through pivot post support.
Static and Dynamic Misalignment Capability
The Flexure Pivot design provides some amount of axial compliance to provide forgiveness of static and dynamic misalignment.
Lower Lubricant Flow Requirements
Special surface preparation and material selection allow Flexure Pivot tilt pad thrust bearings to carry higher loads at lower oil flows, which makes them the bearing of choice for applications where lubricant availability is low.
No Limits on Material Selection
Any material can be used for Flexure Pivot thrust bearings due to the lack of wear and fretting.
The Flexure Pivot thrust pad design permits retrofitting in a small envelope where only taper land or thrust plates would typically fit. This allows space saving and load capacity upgrades for existing thrust bearings.
