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.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
