The pneumatic clutch provides static friction torque of 50Nm to 400Nm at 0.6MPa and is widely used across various industries, including printing, packaging, textiles, rubber, and food machinery. It is suitable for a range of industrial equipment, such as stranding machines, automation machines, coating machines, and paper-making machinery.
Features
- The torque adjustment range is extensive, allowing for broad adjustments through air pressure regulation.
- Pneumatic clutch is safe and reliable, with no electrical sparks generated during operation.
- Suitable for high-frequency and continuous slip conditions, it demonstrates excellent durability even under heavy loads and can function as a torque limiter.
- By adjusting air pressure, pneumatic clutch achieves smooth pneumatic operation, minimizing impact on the system.
- With good heat dissipation, the friction pads experience minimal wear, resulting in a long service life and easy maintenance.
- Its compact design allows for the pulley to be integrated with the clutch, facilitating user convenience.

Structure
Tips: Working principle of pneumatic clutch
The working principle of the pneumatic clutch is as follows: when air is supplied, the piston pushes the disc to compress the friction pads, engaging the clutch. When the air supply is cut off, the reset spring causes the disc to separate from the friction pads, disengaging the clutch. Additionally, the friction pads are designed in a half-open configuration, making them easy to replace.
