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 bearing 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 90.degree. to about 150.degree.. The flat bearing surfaces are defined by inserts formed from a carbide material having excellent wear resistance and independently supported to contact the roll shaft tangentially during operation.
