Belflex Thermbago

Stainless steel bellows coupling Belflex Thermbago

Welded stainless steel bellows coupling for temperatures up to 300°C

The Belflex Thermbago metal bellows coupling, which is completely made of stainless steel, is available in 4 coupling sizes. In this case, the stainless steel bellows is welded with the stainless steel hubs. This procedure ensures that the bellows is permanently connected with the hubs also in critical temperature conditions. As a result, the drive elements have no thermally sensitive connections. The application areas of this Belflex Thermbago are mostly vacuum applications and applications in high-temperature areas up to 300°C.
