Flexure Pivot journal bearing is a type of bearing designed for high-load, high-speed, small-diameter shafts. It achieves low cross-coupling and high stability while eliminating pivot wear, high contact stresses, and pad flutter.

Flexure bearings, which include flexure pivot bearings, are engineered to be compliant in one or more angular degrees of freedom. They serve much of the same function as conventional bearings or hinges but require no lubrication and exhibit very low or no friction.

Flexure Pivot tilt pad thrust bearings are specialized fluid film bearings designed to reduce power loss and extend bearing life over a wide range of speeds, loads, and temperatures. They are ideal for retrofit due to their space-saving design and can increase load capacity, accommodate misalignment, and reduce pivot wear. These bearings form a wedge through flexure of the post support, eliminating pivot wear and high contact stresses associated with point or line contact tilt pad bearings. The custom design of the Flexure Pivot post support to each application provides the optimum wedge ratio at the design load conditions, resulting in greater load capacity and a significant reduction in power loss.

Cantilevered pivot bearings, also known as single-ended pivot bearings, are a type of flexure used in various applications such as gimbal rings, mirror mounts, linkage systems, and vibration isolation systems. These bearings allow one end to rotate in a limited number of degrees when the other end is restrained, making them suitable for supporting overhung loads. They are designed to provide precise and reliable movement without the need for lubrication, which can be beneficial in environments where lubricant outgassing could contaminate sensitive equipment.

Flexure pivot tilt pad bearings are a type of bearing solution designed for high-load, high-speed, and small-diameter shaft applications. They achieve low cross-coupling and high stability while eliminating pivot wear, high contact stresses, and pad flutter.

In these bearings, the tilt pad moves through flexure and rotation of the center post, rather than through a rocking or sliding motion. This design eliminates pivot wear and contact stresses common in high-load, high-speed machines, preventing degradation in performance over time and maintaining the desired bearing preload.
