Product catalog summary
SNX Rotary Joint Overview
The SNX rotary joint is engineered for rotating syphon applications, featuring dual carbon guides for enhanced durability and syphon support. It includes a positive differential seal, suitable for steam and thermal oil applications, and complies with the Pressure Equipment Directive (PED 2014/68/EU) and ATEX standards. Key features include an optimized seal diameter, convex seal ring, and maximum carbon guide separation, ensuring increased reliability and extended seal life.
Type SNX - Concentric and Angled Ports
These configurations offer models with specific dimensions and ratings for steam and thermal oil, with standard ratings of 35 bar for steam and 10 bar for thermal oil, a temperature limit of 288°C, and speeds up to 450 RPM. For higher specifications, factory consultation is recommended.
Syphon Seal Options
Options include an O-ring gland seal for steam and a packing gland seal for thermal oil. The O-ring seal is recommended for ease of installation with a rounded edge on the syphon pipe.
SX Rotary Joint Overview
The SX rotary joint provides a positive seal between stationary piping and a rotating cylinder, using advanced sealing technologies for extended seal life and reliability. It is suitable for steam and thermal oil applications and complies with PED 2014/68/EU and ATEX. Features include a convex seal ring, adjustable syphon clearance, and Silver Streak™ seal ring, offering positive sealing and reduced maintenance.
Type SXA and SXC - Angled and Concentric Ports
These types offer models with specific dimensions and ratings, with standard ratings of 20 bar pressure for steam and 10 bar for thermal oil, and a temperature limit of 288°C. The speed can reach up to 550 RPM. For higher specifications, factory consultation is advised.
Type SXB - Two Ports, 180°
This configuration provides dual flow with specific models and dimensions, maintaining the same standard ratings as other SX types. It offers flexibility in application with various thread types available on request.
Overview: The document provides detailed technical specifications and recommendations for various types of syphon supports and rotary joints, primarily used in steam and thermal oil applications. It emphasizes the benefits of using split wedge syphon supports to enhance performance and reduce maintenance.
Split Wedge Syphon Support: This support is recommended to improve syphon performance and reduce maintenance. It relieves stress in the threads of the cantilevered horizontal syphon pipe, significantly reducing the risk of pipe breakage.
Specifications: The document lists various models of syphon supports and rotary joints, detailing their dimensions, pressure, temperature ratings, and part IDs for both steam and oil applications. Standard ratings include media types (steam and thermal oil), pressure (up to 20 bar for steam and 10 bar for oil), temperature (up to 288°C), and speed (up to 550 RPM).
Types of Rotary Joints: Several types of rotary joints are described, including Type SXBP-1, SXB4, SXBN, and others, each with specific configurations and applications. The SX cartridge is highlighted as an innovative upgrade for existing rotary joints, offering improved seal technology and performance.
Features and Benefits: The document outlines features such as split wedge construction, quick-release flanges, and optimized seal diameters. Benefits include reduced installation and maintenance times, increased reliability, and extended seal life.
Engineered Data: Kadant Johnson seal rings are made from proprietary materials meeting high qualification criteria. The document provides pressure vs. speed and torque vs. pressure data for various rotary joint models.
Recommendations: Filtration requirements should follow machinery manufacturer guidelines. SNX and SX rotary joints are warranted against manufacturing defects for 12 months. Proper installation of flexible hoses is crucial to ensure free movement and eliminate side loading.
Other Rotary Joints: The document also describes other rotary joints like the ELS, ELSN, and RX rotary unions, detailing their applications, sizes, and performance ratings.
Specifications and Applications
The document discusses the G union, which is applicable to spindles, gun drills, milling, and other machinery. It is designed for smooth operation at speeds up to 50,000 RPM and pressures up to 400 bar, available in sizes ranging from 1/4” to 5/8”.
Ordering Information
For ordering a replacement Kadant Johnson rotary union, the Part ID on the product label is required. For new applications or if no Part ID is available, the following data is needed: number of passages, rotor type, rotor thread, supply pipe, service type, fluid pressure, fluid temperature, rotational speed, and connection sizes.
Complementary Products
  • Sight Flow Indicators: These provide visual observation of liquid and non-hazardous gas flows, available in sizes 3/8” to 4”.
  • Pivot Body™ Syphon Elbow: Features a pinless design for improved performance and reliability.
  • Flexible Hose: Designed to prevent pipe strains and enhance flexibility, available in sizes from 1/4” to 8”.
