Radial and axial housing connections with right‑hand female thread G/BSP (ISO 228) or NPT (ANSI). Anti‑rotation device. ATEX certification optional. Set of drain plugs fits Large Series.
Possible Applications
This rotary joint is specifically engineered for high-volume thermal management in heavy industrial machinery, particularly within the paper, steel, and plastics processing sectors. It is ideally suited for large-diameter cooling or heating rolls where a stationary inner pipe is required to facilitate internal fluid circulation without mechanical interference. The robust construction and balanced mechanical seal make it a reliable choice for calendar rolls, drying cylinders, and extruders that operate under continuous duty cycles. By allowing for efficient media transfer in systems requiring high rotational speeds and precise temperature control, this component ensures consistent heat exchange performance in demanding production environments.
