Possible Applications
This rotary joint is specifically deployed in heavy-duty industrial thermal management systems, large calendar rolls, and rubber mixing mills where continuous circulation of cooling or hot water is critical. It is well-suited for high-speed manufacturing lines in the paper, plastics, and textile industries, where rotating drums and cylinders require reliable fluid transfer without mechanical binding. The design accommodates a stationary inner pipe configuration, making it optimal for processes requiring simultaneous supply and return of tempering media within tightly integrated drying and cooling cylinders.
