air chucks

Air ChucksIt is a simple bellow type chuck mounted on an aluminum body for holding up the reel. It is used with a side clamp or a set screw on the base shaft.

Air Chucks

1.      Economical & light weight solution for core holding.

2.      Widely used for low torque unwind operation.

3.      Absolutely no damage to core.

4.      Easy mounting on shaft.Air Chucks


-         Body: Aluminum Alloy

-         Bladder: Rubber Polymer

Available Size:

-         Core ID 5" onwards Bore ID square or round as per customer requirement


1.      Dual non return valve-common air valve for multiple chucks by PU

2.      Stopper plate for core alignment

3.      Bore can be with key-way

Torque Chuck:

Torque ChuckCam type shaft makes the chuck hold core in positive gripping position.

-         Concentric torque chucks expansion.

-         No side arm force required.

-         Gripping is better at high torque application.

-         Comparatively lesser damage to the core.


Alloy steel

Available Size:

-         3", 6", up to 12"


Flange diameter as per customer requirement 

Thrust Chuck:

Thrust ChuckThrust chuck is a tapper wedge design used for core holding where the force is applied through the arms. It is truly mechanical and fool proof in terms of pneumatic.

-         Best suited for rolls using fiber and metal cores.

-         Based on mechanical load provided axially, So fail proof and reliable.

-         This chuck provides absolute holding of the chuck.

-         Concentric core holding.

-         Excellent and fail proof design for rewind and unwind.


-         Base and Flange: Alloy steel

-         Grippers: Hardened steel

Available Size:

-         core: 3" to 12" 

Air Power Chuck:

Air Power ChuckOne of the most heavy and durable core holding option where mechanical advantage of tapper wedge is used through high pressure pneumatic cylinder.

-         Best option for avoiding core damage in shaft less machines.

-         Rotation of the chuck in either direction is possible.

-         No axial force is applied: hence better life of winding and unwinding station.

-         Concentric expansion and gripping force.

-         Quick-Change between core sizes with slide-on core chuck adapters.

-         Unmatched torque capacity at higher speed & jam free operation.

-         Can be used for any core material without alteration.


-         Body: steel

-         Lugs: Alloy steel

-         Springs: Spring steel

Available Size:

-         3", 6" up to 12" 

Lug Chuck:

Lug ChuckPneumatic Core Holding Chuck for Shaft-less winders.

-         Compact & Light weight option for reel holding.

-         Moderate torque capacity for General purpose.

-         No axial force needed for core gripping.

-         Slide on core adaptors available for various core sizes.


-         Housings: Alloy Steel

-         Grippers: Rubber, Plastic

Available Size:

-         3", 4" & 6" on Wards


-         Various Adaptors available 

Multi Bladder Chuck:

Multi Bladder ChuckVariant of the Multi Bladder shaft with through bore inside for holding on a shaft.

-         No direct contract with Rubber Bladder.

-         Less Maintenance cost.

-         Highly Reliable & concentric.

-         Great option for retro fitting existing Shaft or rod.


-         Body : Aluminum, Steel in special case

-         Gripper: Rubber, Plastics and Aluminum
