ABSTRACT:
An outboard water lubricated marine bearing assembly having a cylindrical using and a plurality of stave pads disposed about the inner periphery of the housing for slidably supporting a rotatable shaft extending therethrough. The improvement resides in the stave pad design including a cap of elastomeric material facing the shaft defining a resiliently deformable slidable bearing surface conformable to the shaft and supporting it by a force having a pressure profile progressively increasing across substantially the entire width of the bearing surface from leading to trailing edges thereof for greater overall load carrying capacity.
