ABSTRACT:
A hot dip metal strip coating apparatus includes at least one roll submerged in a bath of molten coating metal for guiding the strip through the bath. The submerged rolls are mounted on the ends of support arms by bearings including a pair of substantially flat metal surfaces disposed in planes parallel to and spaced from the horizontal axis of the roll shaft, with the planes of the flat surfaces intersecting one another at an angle within the range of about 60.degree. to about 135.degree.. The flat bearing surfaces are oriented to contact the roll shaft tangentially, with the load in the strip and the flat bearing surfaces supporting the roll during coating and the bearing permitting the free flow of liquid metal between the bearing and shaft on each side of the tangential line of contact of each flat surface with the shaft.
