Product Features
Rotating Inner Tube
Dynamically adapts to high-speed devices (e.g., rollers, mixers), minimizing wear from relative motion and ensuring sealing reliability during frequent rotation.
Threaded Connection
Vibration-resistant and secure for long-term fixed installation, reducing media leakage risks.
Bidirectional Flow
Supports steam/hot water circulation in both directions.
Material & Performance
The ductile iron housing withstands 220°C and 1.8MPa, suitable for harsh industrial conditions. The six-lobe gland design enables easy maintenance with standard tools, lowering maintenance difficulty.
Summary
The QS-X rotary joint, with its rotating inner tube and threaded connection, is designed for high-speed rotating equipment, combining dynamic sealing reliability and installation stability. It serves as an efficient solution for hydraulic machinery, plastic calendering, coating equipment, and other industrial applications.
