Abstract

A roller may be used to deflect or guide a metal strip to be coated in a metal melt bath. The roller may comprise a steel roller shell and steel bearing journals that are connected to the roller shell and arranged coaxially to each other for a rotary supporting of the roller. Disposed on each bearing journal may be a substantially cylindrical or circular disk-shaped connection portion that is made of steel and that extends radially in a direction of the roller shell. At least one of the connection portions may have at least one through opening that emerges at an end face of the roller shell. Further, a filling made of one or more filling elements that have at least one closed cavity may be arranged in the roller shell. The filling may have a structure that is symmetrical about an axis of rotation of the roller.
