Core Shafts
Core shafts securely hold rolls for winding and unwinding in various industries with minimal runout and maximum torque transmission.

Overview
About Core Shafts
Core shafts are essential components in flexographic printing machines. They serve as the central support for the printing plates and the rolls of substrate material (like paper, film, or foil). These shafts ensure that the printing plates and substrate maintain a consistent and precise alignment during the printing process.

06Pneumatic Expanding Shafts (PES)
Pneumatic expanding shaft with lugs model BUTLER is primarily recommended for unwinding and winding rolls that have cores when a high torque to be transmitted and heavy working conditions is required. The body of the shaft is available in a variety of high- strength steels; the expanding lugs come in either steel with an aggressive profile or plastic depending upon core material and torque requirements.The journal ends are also available in a variety of steels and are always custom- made.Expansion is accomplished by a single inflatable tube which pushes on the expandors when air is applied.An exclusive tube protector works to substantially reduce wear and potential rubber tube leakage.Models ordered with journals bigger than 50 mm diameter can be fitted with the SVECOM quick - change air tube, which will allows you to change rubber tubes without removing the shaft from the roll or the machine.
07Multi Tube Air Expanding Shaft(MTS-4000)
Multi Tube Air Shaft provides superior performance for winding and unwinding process in all types of printing & packaging industries. Multi Tube Air Shaft features durable hard multi-bladder for gripping the inside diameter of any type of cores. Multi Tube Air Shaft can be run on multiple and large diameter cores. It gives and equalizes tension during working time.
08Slitter Knife Shaft(SKS-1280)
Slitter Knife Shaft is manufactured from high quality alloy steel. This shaft body is hard chrome plated and precision ground to match the inside diameter of your current anvils. Slitter Knife Shafts are available in custom diameter, length. This shaft is dynamically balanced and precision ground & chromed to the most precise tolerances. Outer body holds the anvils or knives
09Heavy Duty Mill Shaft(HDS-1250)
Heavy Duty Mill Shaft is manufactured for use in production of Jumbo Rolls Tissue and Paper Industry & Steel Industry. Heavy Duty Mill Shaft is manufactured in two types – Lugs Type or Multi Tube Type. Heavy Duty Mill Shafts are available in custom diameter & length. This shaft is dynamically balanced and precision ground & chromed to the most precise tolerance.
10Multi Tube Cantilever Shaft(MCS-2850)
Cantiliver Shafts are widely used for pouching machines, doctoring machines, & label printing machines. Cantiliver Shafts have a durable construction to hold the cores for positive gripping. They are in fange mounting styles and are used for light to medium duty works.

Button Air Expanding Shaft rugged construction and design is available for any diameter or length, in steel or aluminum with special designs available for heavy duty and light weight applications. We manufacture to your specifcations to suit your equipment, including standard or varied button spacing, cantilevered or custom designed.
12Carbon Fiber Air Expanding Shafts (CAS-1500)
Carbon fiber pneumatic expanding shaft with lugs model 638 PK is recommended for unwinding and winding of coils with cores. is recommended for unwinding and winding of coils with cores. The shaft body is made of high resistance carbon fiber, fabricated through filament winding technology and, on request, it can be protected externally by a steel casing. This shaft is extremely light compared to traditional solutions and it allows better productivity because: It can work at higher speed It can be managed by a single operator without assistance It does not require the use of lifting systems for its insertion into the coil and for extraction from it The expansion is obtained thanks to a single rubber tube which, once inflated, pushes the lugs outwards and allows the locking of the cores. The protection system ensures a longer life of the pipe, reducing the possibility of breakage. The journal ends are always made according to the customer’s drawing. On models with side journal ends with a diameter bigger than 50mm, it is possible to provide a system for the quick disassembly of the rubber pipe in the event of breakage, allowing to repair the shaft in minimum time.
