Trusted Hydraulic Rotary Union Joint for Diverse Industrial Fluid Systems

Description

Product Overview

The H Type Rotary Union Joint is a high-precision rotary sealing device engineered for fluid transfer between stationary and rotating components. Designed specifically for high-speed, high-pressure, and multi-application industrial systems, this rotary union excels in transferring steam, water, oil, air, and other media in both single- and dual-passage configurations.

With robust internal construction and a modular body design, the H Type Rotary Union Joint provides excellent sealing performance, reduced torque resistance, and long service life. It is ideal for applications where compact size, stability, and reliability are critical.

Technical Specifications

Key Features

Dual-Passage Design (H-Type Structure)

Supports simultaneous flow of different media or supply and return lines, improving efficiency and saving space.

High-Pressure & High-Speed Capable

Handles up to 20 bar pressure and 3000 RPM, depending on model and media.

Long-Lasting Sealing System

Equipped with advanced carbon graphite, ceramic, or silicon carbide seals to prevent leaks under tough operating conditions.

Self-Supporting or Housing-Mounted Options

Offers flexible mounting types to fit various machine configurations.

Corrosion-Resistant Body

Made with anodized aluminum, brass, or stainless steel for long-term performance in harsh environments.

Our seals are on CNC machine tools and special grinding machines. The finished, mirror-like surface makes the seal more reliable, and high-precision rolling bearings are also used to make it rotate smoothly.

Applicaiton

The H Type Rotary Union Joint is engineered for dual-flow applications, making it ideal for industrial systems that require simultaneous media supply and return, such as cooling/heating loops, hydraulic circuits, and spray systems.

FAQ

Q1: What is the difference between an H-type and a standard rotary union?

A: The H type has a dual-flow design, allowing simultaneous inlet and outlet media flow, often used for cooling and return circuits.

Q2: Can I use this rotary union for high-temperature steam?

A: Yes. We offer high-temperature models with silicon carbide seals and stainless steel bodies for steam use.

Q3: Do you offer installation accessories or mounting brackets?

A: Yes. We can supply brackets, adapters, and flexible hoses upon request.

Q4: How can I choose the correct size and configuration?

A: Send us your application details (media, pressure, speed, connection type), and our engineers will recommend the best-fit model.

Q5: Is sample testing available?

A: Yes. We support small-quantity trial orders and offer samples for testing.
