Dongguan Synectics Machinery Technology Co,.Ltd
Air shaft include Lug (key) type (steel-made or ally-made) and lath type.
Air shaft is a special shaft for winding and unwinding. The shaft is created by the key
on the surface, which will be expand when the high-pressure gas filled in the shaft.
Air shaft is easy to operate, the user only have the air supply with the air pressure
controlled within 6-8kg/cm2. Just aired the shaft through the air valve and when user
want to lock the web. Just push the core activities of the air valve to deflate, the keys
will revert to its original appearance, then web can be removed easily.
Air shaft is widely used for winding, rewinding and slitting machines. It is widely used in printing, packaging, plastics, paper, glass, pharmaceuticals, electronic battery, textile machine and industry.

The External Strip Shaft is ideal for light and medium duty unwind or rewind applications. Evenly spaced rows of continuous rubber lugs accomplish the gripping action in this type of shaft. The larger area of the external lug allows for a higher torque capacity. Total load carrying capacity is some what sacrificed as the outside body tube surface is machined away to allow for multiple “T” slots design to accommodate the rubber lug. The continuous lug design allows for the mounting of multiple cores of any width. The synectics external strip lug shaft is simple in construction allowing for each external lug strip to be changed without dismantling the shaft.

Slitter Rewinder Core Shaft – Important Characteristics
- For multiple slit rewinding.
- Simple clamping unit secures bladder/gripping element assembly for easy maintenance.
- Durable hard rubber grippers offer excellent core grip.
- Protective Teflon strip covers bladder to reduce liklihoodof bladder failure.
- Brass air valve resists corrosion.
Expanding External Element Gripping Shafts
- Core shaft diameters starting at one inch.
- Multiple external expansion elements to grip the inside diameter of any core material.
- Gripping elements are activated by simultaneously inflating bladders with a single air valve.
- While bladders rarely fail (because of our proprietary material and metal protection strip), the process to replace one is simple and quick. Likewise, the gripping element can be replaced easily by loosening a single set screw in the clamping unit.
- Hard rubber elements are standard; silicone and aluminum are available to suit various applications.
- Minimizes core distortion and wall damage.
- Economical to purchase and maintain.
Ultra-Lightweight Strip Shafts for Six-Inch Cores
Brand New Design!
Lighter and stronger 6-inch diameter core shafts for multiple slit winding applications.
- Double E Ultra-Lightweight Strip ShaftsProprietary aluminum extrusion minimizes shaft weight in both light and heavy–duty applications (over 20% lighter than Double E’s standard SR–2000 strip shaft while maintaining the same strength).
- Brass air valves for corrosion resistance, custom–made steel journals,
- Aircraft–grade aluminum bodies.
- High–performance bladders and rugged gripping elements.
