A beating assembly for a submersible motor/propeller unit for a water vehicle consists of a radial bearing assembly and a thrust bearing assembly associated with a propeller and an axle. The radial and thrust bearing assemblies are comprised of bearing components, preferably made of a hard material to provide 'hard-on-hard' bearing surfaces, and a resilient backing means, preferably rubber, positioned behind the stationary bearing component. The 'hard-on-hard' bearing surfaces increase the load capacity and operating life of the bearings, and the resilient backing means allows the propeller to be displaced under high impact shock loads and to transfer the shock loads to shock snubber locations between the rotor and the stator. The combination of 'hard-on-hard' bearings with the resilient backing means provides control of the centering of the propeller on the shaft and longer operating life for the propeller unit, as well as increased capability to survive high shock loads.

A liquid metal pump bearing support comprises a series of tangentially oriented spokes that connect the bearing cylinder to the pump internals structure. The spokes may be arranged in a plurality of planes extending from the bearing cylinder to the pump internals with the spokes in one plane being arranged alternately with those in the next plane. The bearing support structure provides the pump with sufficient lateral support for the bearing structure together with the capability of accommodating differential thermal expansion without adversely affecting pump performance.

A gravity assisted anti-reverse rotation device for preventing reverse rotation of pumps and the like. A horizontally mounted pawl is disposed to mesh with a fixed ratchet preventing reverse rotation when the pawl is advanced into intercourse with the ratchet by a vertically mounted lever having a lumped mass. Gravitation action on the lumped mass urges the pawl into mesh with the ratchet, while centrifugal force on the lumped mass during forward, allowed rotation retracts the pawl away from the ratchet.
