Abstract
A sleeve/rod type squeeze bearing system is disclosed in which the cross-sectional geometry of the piezoceramic bearing driving element is geometrically dissimilar to the cross-sectional geometry of the bearing element to which it is connected. The arrangement permits the cross-sectional geometries of both bearing elements and the piezoceramic driving element to be optimized to perform their intended functions.
