Cantilevered single part flexure bearings are precision-engineered pivot bearings designed to provide frictionless, backlash-free rotational motion over limited angular ranges. These flexible bearings consist of a cantilevered arm or leaf spring that flexes elastically to allow smooth motion while maintaining high radial and axial stiffness. Their unique design offers exceptional repeatability, high load capacity, no metal-to-metal contact, resistance to fretting corrosion, and maintenance-free operation. Ideal for delicate and precise positioning applications, they combine durability with compactness in a single integrated component.

Flexure Pivot journal bearings are advanced tilt pad bearings designed for high-load, high-speed, and small-diameter shafts, offering exceptional durability and rotordynamic stability. The unique design incorporates an integral pad-pivot-retainer where the bearing pad flexes via a center post, eliminating pivot wear, contact stresses, and pad flutter common in traditional tilt pad bearings. This results in longer bearing life, consistent preload, reduced vibration, and improved rotor stability across varying operational conditions. The compact, one-piece construction ensures minimal manufacturing tolerance stack-up, enhancing rotor critical speed and synchronous response.
