Fluid Rotary Joint for Hydraulic and Pneumatic Applications

Description

Product Overview

The H Type Fluid Rotary Joint is a versatile and high-performance rotary union engineered for reliable fluid transmission between fixed and rotating equipment. Designed for industrial use, this joint offers a balanced seal structure and robust bearing system that supports high-pressure, high-speed, and high-temperature environments.

Whether transferring water, steam, thermal oil, or air, the H-type rotary joint ensures stable media flow with minimal leakage, making it an ideal solution for machinery in steel mills, textile plants, paper manufacturing, and plastic molding.

Manufactured with hardened alloys and precision machining, this fluid rotary joint offers long service life, reduced maintenance, and customizable interfaces to match specific operational needs.

Key Features of the fluid rotary joint

🔩 Robust Construction for Long-Term Reliability

Our fluid rotary joints are manufactured using high-grade stainless steel, brass, or aluminum alloy, offering superior resistance to corrosion, wear, and thermal expansion. The hardened rotor surface and precision-machined seals ensure minimal internal leakage even under high pressure.

🔧 Advanced Sealing Technology

Each unit incorporates carbon-graphite, mechanical, or elastomeric seals, specially designed to withstand the operating media and temperature range. These zero-leakage seals help avoid costly downtime and contamination.

⚙️ Smooth Rotational Performance

Equipped with high-precision bearings and a dynamically balanced rotor, the joint maintains low-friction torque and stable rotation, even at speeds up to 10,000 RPM. This results in reduced mechanical stress and enhanced operational efficiency.

🌡️ Wide Temperature and Pressure Range

From -30°C to 250°C and with pressure ratings of up to 300 bar, our fluid rotary joints can withstand extreme industrial environments. Optional cooling jackets are available for high-temperature applications.

🔄 Single, Dual & Multi-Passage Configurations

Choose from a variety of single-flow, dual-flow, or multi-passage rotary unions to suit your operational needs. Our multi-port designs support the simultaneous transfer of different media (e.g., hydraulic fluid and coolant) without cross-contamination.

🧩 Customizable Interface Options

We offer a full selection of threaded, flanged, and quick-connect adapters to match different shaft sizes, pipe fittings, or OEM equipment requirements.

🛠️ Low Maintenance & Easy Installation

Designed for minimal service requirements, most units are pre-lubricated for life and feature a modular design for fast installation and replacement.

Applications

Textile Industry

The H-type joint supplies hot water and steam to rotating dyeing machines and drying drums. It ensures even heating and prevents condensation buildup during fabric processing.

Paper Manufacturing

In drying cylinders and calender rolls, the joint allows for efficient thermal oil or steam flow. Its high sealing performance supports continuous operation under high load and temperature.

Plastic and Rubber Machinery

Molding systems use this rotary joint to control temperature via hot oil or water in rotating molds. It helps stabilize mold temperature and reduces cycle times.

Steel Rolling Mills

Rotating components, such as cooling drums or roll chocks, require consistent water flow. The joint’s pressure and heat resistance make it ideal for these harsh environments.

Food Processing

Steam and water rotary transmission is common in rotating ovens or cookers. The H-type rotary joint meets hygiene and temperature demands safely and efficiently.
