Rotary Union Pneumatic Clutch

Description

The Rotary Union Pneumatic Clutch is an advanced air-transfer and torque-transmission device designed for machinery that requires simultaneous rotation and pneumatic power delivery. It combines the functionality of a rotary air union and a pneumatic clutch system, allowing compressed air to flow seamlessly between stationary and rotating components while transmitting torque with precision and reliability.

This innovative design enables engineers to operate air-actuated mechanisms in rotating systems without leakage, vibration, or air loss—ensuring stable and efficient performance even under high-speed or high-pressure conditions.

Key Features

• Integrated Air and Power Transfer:
  Efficiently transfers compressed air through rotating assemblies while enabling torque engagement or disengagement.

• Leak-Free Performance:
  Precision sealing technology prevents air loss and contamination, ensuring clean and reliable pneumatic control.

• Durable Construction:
  Built with hardened stainless-steel components, carbon graphite seals, and high-grade aluminum housings for long service life.

• Compact and Modular Design:
  Space-saving structure simplifies integration into existing machinery and allows quick installation or replacement.

• High-Speed Capability:
  Dynamically balanced for smooth rotation and minimal wear at high speeds.

• Low Maintenance:
  Self-lubricating seals and precision bearings minimize maintenance downtime and extend operational lifespan.

Working Principle

The Rotary Union Pneumatic Clutch integrates an air rotary union and a clutch mechanism into one compact assembly.
Compressed air enters through the stationary port and passes through internal sealing channels to the rotating shaft. When air pressure is applied, the clutch engages and transmits torque to the rotating member. When air pressure is released, the clutch disengages, stopping torque transmission while maintaining air integrity.

This dual-function design ensures precise control over rotation, engagement, and pneumatic actuation—ideal for automation systems, robotics, and high-speed production lines.

Applications

The Rotary Union Pneumatic Clutch is widely used in industries where air pressure and rotation must coexist without leakage or mechanical interference, including:

• Packaging Machinery – for pneumatic cylinder actuation in rotating filling or sealing stations.

• Printing and Converting Equipment – for roll tension control and air-actuated clutches.

• Robotics and Automation Systems – to control air-driven grippers, spindles, and rotary actuators.

• Textile Machines – for synchronized air supply to rotating components.

• Machine Tools and CNC Equipment – for air chuck operation and automatic tool change mechanisms.

• Automotive and Tire Industry – for pneumatic clutch control and rotary air distribution.
