Key Features of Deublin 1205-000-003 Rotary Union Replacement

Single-Passage Design

Specifically engineered with a single-flow passage, this rotary union ensures reliable transfer of coolant, air, or hydraulic media without leakage. The simple flow path minimizes pressure drop and enhances operational efficiency.

Self-Supported Rotating Swivel Joint

Designed as a self-supported unit, the rotary joint does not require additional support structures, reducing installation complexity and ensuring stable operation in high-speed environments.

Radial Housing Connection

Features a radial housing port that allows flexible connection to a wide range of machine tool systems. This design simplifies integration into existing coolant or air delivery systems.

Balanced Mechanical Seals

The rotary union uses precision-balanced mechanical seals, minimizing wear while maintaining consistent sealing performance under high rotational speeds and demanding conditions.

Advanced Seal Combinations

Offers multiple seal material options such as carbon-graphite with hardened tool steel or carbon-graphite with silicon carbide. These options allow customization based on the operating environment, ensuring long service life and compatibility with various media.

Felt Lubricator for Air Service

Includes a felt lubricator integrated into the seal chamber, providing continuous lubrication during air service applications. This extends seal life and maintains consistent performance.

Grease Fitting for Easy Relubrication

Equipped with a grease fitting that allows convenient relubrication. Recommended maintenance of 3–5 drops per month ensures the unit remains in peak working condition with minimal downtime.

Low-Torque Operation

Engineered for reduced torque resistance, this design enhances efficiency and reduces energy consumption, making it ideal for continuous operation in CNC machines and molding equipment.

Weight-Optimized Construction

Lightweight yet durable construction helps reduce machine load while maintaining robust performance, particularly in dynamic high-speed machining processes.

Corrosion-Resistant Housing and Rotor Options

Built with anodized aluminum housing for excellent corrosion resistance, paired with either stainless steel or carbon steel rotors, depending on model specifications. This ensures strength, longevity, and compatibility with demanding industrial conditions.

Permanently Lubricated Ball Bearings

Features deep-groove, permanently lubricated ball bearings that support smooth rotation and reduce the need for frequent maintenance. This design guarantees consistent performance even under continuous operation.
