Date Jul. 19, 1984.Tubular, pneumatic, vibratory transducer bearings incorporate a pair of colinear nested tubes with differing radii joined together at their inner and outer radii respectively. The mode of oscillation of the structure is designed to produce minimal vibration of the load carried on points of low vibration on the surface of the inner tube. The inner tube is far longer than the outer tube which is piezoelectrically excited at the correct frequency to produce the mode of oscillation desired for low vibration, automatically or self-pressurized bearing arrangement. The tubes are cylindrical and the inner tube rides on a cylindrical rod. The mounting points are at saddle points on the surface of the inner tube. The shortness of the outer tube of the transducer reduces the weight of the transducer.
