Roller for deflecting or guiding a metal strip to be coated in a metal melt bath

A roller for deflecting or guiding a metal strip to be coated in a metal melt bath, the roller comprising:

• a steel roller shell;
• steel bearing journals that are connected to the steel roller shell and are disposed coaxially to each other for a rotary supporting of the roller;
• a connection portion disposed on each of the steel bearing journals, each connection portion being substantially cylindrical or circular disk shaped and being comprised of steel, wherein each connection portion extends radially in a direction of the roller shell, wherein at least one of the connection portions includes a through opening that emerges at an end face of the steel roller shell;
• and
• a filling comprised of one or more filling elements that have a closed cavity, the filling being disposed in the steel roller shell, wherein the filling comprises a structure that is symmetrical about an axis of rotation of the roller,
• wherein the one or more filling elements comprise one or more longitudinal profiles that contain at least one hollow profile that is closed at both ends.
