The present method produces composite bodies, such as steel mill rollers, having a core and a jacket, by providing initially prior to shrinking the jacket onto the core, a gap between the core and the jacket with a width which varies over the length of the jacket especially as a function of the loads, such as the shearing load, whereby a more favorable load carrying capacity and thus an extended service life are obtained. Preferably, the roller has a core with a convex surface and the jacket has a wall thickness which increases from the edges of the jacket towards the center of the jacket to provide either a cylindrical or convex outer surface for the finished roller.
