Abstract
A self-aligning, vibration reducing marine thrust bearing assembly for use ith a propulsion shaft having spaced bearing flanges. The assembly includes a journal bearing sleeve enclosing the shaft and a stationary housing radially spaced from the journal bearing with pivoting means extending therebetween for accommodating any misalignment of the shaft and journal bearing within the housing. An annular fluid containing cavity is formed in the housing adjacent each flange with an annular bearing piston pivotally disposed therein, wherein sealing elements are positioned between the cavity walls and the piston to maintain a fluid seal therebetween. Tapered roller bearings are disposed between each annular bearing piston and each shaft flange raceway.
