Pneumatic Expanding Shaft and Core Chuck Adapter
Mechanical Core Chucks: The gas expansion sleeve is also called the inflation sleeve, or the inflation sleeve. Inflatable sleeve: used to match 3 inch air expansion shaft (air expansion shaft with diameter of 74 or 75), 3 inch air expansion shaft sleeve clamp, can take up the raw material with large diameter of paper tube, can replace 6 inch inflation The shaft is used to rewind and unwind large diameter items with higher manufacturability.
1. Structural features: The gas riser sleeve mainly consists of front sleeve, rear sleeve, cylinder, inner tube, airbag and convex keyboard. The riser material is made of high-quality aluminum, oxidized on the surface, equipped with high-quality airbags and fast inflation nozzles. Good sealing effect, long service life and convenient maintenance.
Advantages: light weight and convenient loading and unloading.
2, product specifications: divided into a button-type inflatable sleeve and a plate-type inflatable sleeve. Common specifications are: 3 inches to 6 inches, 3 inches to 8 inches, 3 inches to 10 inches, 3 inches to 12 inches. After inflation, the diameter increased by 8mm. The length is 200 mm, 250 mm, 300 mm, 400 mm, 500 mm, etc. (Can be customized according to customer needs, length is not limited)
Inflatable sleeve clamp technical parameters: air expansion sleeve body outer diameter Φ150mm, action outer diameter Φ155mm, suitable for paper tube Φ149-153mm, 201-205mm, 252-256mm, 302-305mm body length 200mm, 250mm, 300mm, 400mm, 500mm, etc. .
3. Application of inflatable sleeve clamp: It can be fixed at any position of the inflation shaft to facilitate winding and unwinding. The rise sleeve is suitable for the retracting of related machinery such as coating, printing, rewinding, paper making, plastics, etc. .


Benefits of converters:
• Dramatically improve splice reliability.
• Increase operating speeds.
• Save time and money with repeated use of cores without damaging core ends, which can lead to excessive dust.
Wide-footprint shaft lugs provide a consistent grip on the core, without damaging the inside. Removal is easy with pneumatic and mechanical retraction of lugs that ensure the lugs never stick to the core.
Convertech’s Expanding Shaft and Chuck Adapters are available with your choice of:
• mechanical or pneumatic expansions
• set screw or clamp collar designs
Combine Convertech’s Mechanical or Pneumatic/Mechanical Chucks with our expanding adapters and you’ll be able to use more core diameters without purchasing additional shafts and chucks.
