ABSTRACT OF THE DISCLOSURE A journaled bearing assembly including a pair of semi- circular half shells defining a sleeve bearing with an outer sur- face and an inner bearing surface with the surfaces extending axially between laterally spaced opposite ends and circumferential- ly between oppositely disposed parting faces with the bearing sur- face being concave and the outer surface being convex axially be- tween the ends while in the free state. The bearing sleeve is disposed in a bearing pocket in a rod and crank shaft assembly with the bearing surfaces in engagement with a journaled portion of a shaft. The bearing pocket in the piston rod includes clamping members in clamping engagement with the outer surfaces of the half shells to apply radial forces to the half shells to force the con- cave and convex surfaces into a straight configuration axially between the ends thereof so that the stresses in the half shells are greater along the circumferential center line than along the circumferential ends whereby the seating pressure between the bearing sleeve and the pocket are greater along the circumferential center line of the outer surface of the bearing sleeve than along the portions of the outer surface adjacent the circumferential ends to thereby allow any oil between the outer cylindrical surface of the bearing sleeve and the pocket to follow the path of least resistance and flow from the circumferential center line out the ends from between the bearing sleeve and the pocket. Thus, any protective coatings on the outer surface of the bearing which wears free and any build-up of oil oxides are continually flushed out the ends of the bearing sleeve.
