Patent ID: 8602955

Claim:
A furnace roller assembly comprising: a furnace roller shaft having an outer surface; at least one shaft-offset and metal product contact surface assembly helically wound around the outer surface of the furnace roller shaft extending in an axial direction along a length of the furnace roller shaft, the at least one shaft-offset and metal product contact surface assembly comprising: a wear element; a cooling element connected to the wear element, the cooling element having an internal coolant passage terminating at opposing cooling element supply and return ends at an offset assembly supply and return coolant openings, respectively, located along the length of the furnace roller shaft; and an elongated planar support plate between the outer surface of the furnace roller shaft and the cooling element to radially offset the cooling element and the wear element from the outer surface of the furnace roller shaft, wherein the support plate includes a first planar edge connected to outer surface of the furnace roller shaft so that the plane of the support plate extends radially from the outer surface of the furnace roller shaft and a second planar edge connected to the cooling element, wherein the second planar edge is on a side of the support plate opposite to the first planar edge.
