Abstract
A pivot bearing comprises an outer ring-like structure and an inner concentric central structure. Each structure holds cams usually having one type of contour, an involute contour on the outer structure and a cylindrical contour on the inner structure e.g. Flexible pendulums cut to length are affixed at one end to each individual cam of the outer involute cams and at their opposite ends to each individual cylindrical cam. The intermediate area of the pendulums between the fixed positions of flexible pendulums tautly and contiguously envelop the cam contours. The center structure, which may serve as a shaft, is held concentric and free to pivot from one ambit to the other ambit in apposition to each position.
