PNEUMATIC WINDING EQUIPMENT
Engineered around your process.
Jiacheng configures air expanding shafts around the paper core size, face length, roll weight, operating speed, torque and machine interface. Shaft body, expanding elements, journals and air connection are coordinated for practical handling and reliable roll support.
Application Fit
Body diameter, face length and journal details are matched to the winding position.
Practical Operation
Simple pneumatic expansion supports efficient loading, unloading and roll changes.
OPERATING BENEFITS
What this equipment improves.
Reliable core gripping
Expanding elements distribute contact along the core for winding and unwinding duty.
Efficient roll changes
Pneumatic expansion supports practical loading, release and changeover.
Custom journal interfaces
Shaft ends can be machined to match the customer’s bearings, chucks or drive connection.
Duty-based construction
Body, expanding mechanism and journals are selected around roll weight, speed and torque.

FREQUENTLY ASKED QUESTIONS
Useful details before inquiry.
Which data is needed for quotation?+
Please provide core inside diameter, roll width and weight, speed, torque, journal drawing, air pressure and the winding position.
Can the shaft ends match an existing machine?+
Yes. Both journal ends can be manufactured to an approved customer drawing after bearing and drive interfaces are verified.
How is the shaft checked before shipment?+
Checks can include key dimensions, expansion and release, air tightness, surface condition and functional operation.
