Adaptors are the most economical solution to adjust an existing shaft to a larger core diameter. Mounting and dismounting takes just a few seconds, saving time and the cost of a new expanding shaft. Leaf / Lugs adaptors can be made in virtually any size according to customer requirements, starting from 3” diameter. Our expanding sleeves are mounted on 3” expanding shafts to clamp cores with a larger diameter up to 12”. Standard diameters are 3”, 4” and 6”.

Axial-thrust mechanical chucks with double diameter cores 3” and 6”. The chuck expansion occurs by axial thrust of the chuck inside the core. The lugs are kept at the minimum diameter with the help of spring force. FORTUNE axial thrust mechanical core chucks are provided with a spring system which, using the axial thrust when introduced inside the reel core, expands a series of keys.

The 1 Inch Multi-Bladder Air Shaft is a precision-engineered solution designed for secure and uniform core gripping in slitting, rewinding, and converting applications. Featuring multiple inflatable bladders, it ensures even air distribution across the core, providing superior grip strength while minimizing core damage and slippage. Ideal for handling lightweight and narrow rolls, this air shaft enhances machine efficiency, ensures smooth operation at high speeds, and reduces downtime. Manufactured using high-quality materials for durability and long service life, it is widely used in industries such as flexible packaging, paper, and film processing, making it a reliable choice for consistent and high-performance roll handling.
