Pneumatic safety chuck

for winding shaft

Overview
Designed to hold double-supported expanding shafts and transmit power, acting as the interface between a motor/brake and the expanding roll shaft.

Operation

• Semi-automatic opening via a solenoid valve that operates two pneumatic cylinders integrated in the support.
• Active safety system with rotation-point sensing to indicate whether opening is safe (anti-opening function).
• Opening is actuated by a button or lever positioned in an operator-friendly area.
• Contact area with the expanding shaft is interchangeable and treated by gas nitriding to provide high surface hardness and extended service life.
• Load capacity mentioned in page text: 3,500 kg.

Contact area and treatment
The interchangeable contact area features gas nitriding surface treatment for improved hardness and longevity of wearable components.

Assembly

• Flange Mounted
• Foot Mounted
