Abstract
The size of a bearing 34 required to journal a propeller 16 may be reduced by mounting the bearing 34 on a piston 44 received in a cylinder 46 and by locating a piston 62 in a groove 52 on the hub 18 of the propeller 16. The groove 52 acts as a second cylinder and opens oppositely of the cylinder 46. The two are interconnected by bores and ports 64, 66, 68, 70 and filled with an incompressible fluid.
