This  core airshaft size is 3inch ,total length is  precision inflating core airshaft is designed and produced by shanghai handong machinery .It  features 0.1 mm concentricity at the tensioned sleeve, 

True concentric expansion for high–speed and/or heavyweight winding applications.  Mechanical fail-safe operation and positive lug retraction.

pneumatic mechanical shaft utilizes a unique “air-down” gripping system which combined

the benefits of concentric expansion with the convenience of air retraction.

Lugs grip the core automatically when the shaft is vented;  lugs collapse when air is added.

a rugged design for heavy loads, and compatibility with high-quality pressure pieces. 

It can also be supplied with a measuring scale and stop ring.
