A roller assembly for moving a billet in a furnace comprising a rotatable shaft, a roller and at least one support member. The roller has an outer rolling surface for accepting the billet thereon. The roller further includes an inner surface. The at least one support member is located between the rotatable shaft and the roller. The at least one support member includes a support surface engaging the inner surface of the roller, whereby the support surface provides support for the rolling surface of the roller, thereby preventing cracking or indenting of the rolling surface as the billet strikes the rolling surface.
