Abstract

A system includes a device, a support structure, and a flexure bearing configured to connect the device to the support structure. The flexure bearing includes an outer hub and an inner hub, where the hubs are configured to be secured to the support structure and to the device. The flexure bearing also includes multiple sets of flexure arms connecting the outer hub and the inner hub, where each set of flexure arms includes symmetric flexure arms. The flexure bearing further includes multiple bridges, where each bridge connects one of the flexure arms in one set of flexure arms to one of the flexure arms in an adjacent set of flexure arms.
