Product Overview

The High Rotary Joint is a push-in fitting designed specifically for high-speed swiveling and swinging applications where continuous rotation and dynamic movement are required. It ensures reliable fluid or gas transfer while maintaining mechanical stability under rotational stress, making it ideal for use in systems that demand frequent motion without loss of seal integrity or performance.

Construction and Materials

The joint features PBT resin for its primary structural components, a standard material well-suited for general environmental conditions. The metal parts are constructed from brass with electroless nickel plating, providing excellent corrosion resistance and durability under operational stress. Seal materials include both NBR and FKM rubber, with FKM offering superior performance in heat, chemical, and ozone resistance—ensuring robust sealing across a range of operating environments.

Configuration and Connections

The rotary joint is configured with two ball bearings to support high-speed swiveling and swinging motions where conventional rotary joints may not perform adequately. It features a push-in fitting design that allows for quick and secure assembly without the need for tools, enabling efficient installation in dynamic systems requiring rotational movement.

Operating Characteristics

Operational specifications include a maximum operating pressure of 1.0MPa, a maximum vacuum capacity of -100kPa, and an operating temperature range from 0℃ to 60℃ (no freezing). The joint is rated for air as the fluid medium and is designed to reduce load on moving parts while preventing tube twisting during operation.

Sizes and Options

Available in multiple sizes including φ4, φ6, φ8, φ10, and φ12 mm (equivalent to φ5/32", φ3/16", φ1/4", φ5/16", φ3/8", φ1/2"), the joint offers a range of options to match various system requirements. Threaded connections are available in metric male threads M5x0.8 and M6x1, as well as taper pipe threads R1/8, R1/4, R3/8, R1/2 (male) and Rc1/8, Rc1/4, Rc3/8, Rc1/2 (female), and UNF 10-32UNF or NPT1/8, NPT1/4, NPT3/8, NPT1/2.

Installation and Integration

The joint integrates directly into systems via its push-in fitting design and threaded interfaces. It supports installation using standard metric male threads (M5x0.8, M6x1), taper pipe male or female threads (R or Rc series), or UNF and NPT threads, allowing seamless integration with a wide range of piping and fluid delivery systems.
