ABSTRACT:
A sleeve/rod type squeeze bearing system is disclosed in which the piezoceramic driving element is placed in compression to an extent that limits or eliminates stress reversals of the piezoceramic driving element during vibrating cycles. Eliminating or limiting stress reversals increases reliability of the bearing system and extends the useful life of the bearing elements. The bearing load of such a system may also be increased.
