The H Series Rotary Union is a versatile and reliable rotary joint specifically engineered for transferring cooling water, steam, heat transfer oil, and other fluids in rotating machinery. Known for its zero-leakage performance and long service life, the H Series is widely used across industries such as paper, plastics, textiles, metallurgy, and food processing. This series combines advanced sealing technology with robust construction to ensure high reliability under demanding operating conditions.
2–8 fluid/electrical channels with independent sealing systems for cross-contamination prevention.
Stainless steel (316L), aluminum alloy, or engineering-grade polymers for corrosion resistance.
Up to 2000 PSI (13.8 MPa) per channel, with high-pressure variants available for hydraulic systems.
-20°C to 180°C (-4°F to 356°F), suitable for hot oil, water, and compressed air.
Smooth operation at 3000 RPM (up to 5000 RPM for specialized high-speed models).
PTFE composite seals with spring-loaded designs for minimal wear and zero leakage.
The H Series Rotary Union excels in precision-driven industries, including:
Transfers ink, air, and vacuum pressure in rotary presses for multi-color printing.
Manages steam, lubricant, and control signals in circular knitting machines.
Transmits hot water, sanitizers, and pneumatic power in automated bottling lines.
Delivers coolant and lubricant to rotating tool holders while transmitting encoder signals.
Integrates with hydraulic actuators and electrical slip rings for multi-axis movement in automotive assembly.
Easily configurable channel layouts reduce customization lead times for unique industrial needs.
Quick-release cartridge seals enable maintenance without disassembling the entire system.
Low-friction bearings and precision machining minimize power loss in high-speed operations.
Compliant with ISO 14001 (environmental) and ISO 44001 (quality management) standards.
