Safety Chucks


This safety chuck for the dragging and rotation of the expanding shafts is conceptually different from any others actually present on the market and it is particularly indicated for very high rotation speeds that is absolutely vibration-free and silent because there is no clearance between the bearing mounted on the shaft journal and its seat.

Available in 3 models: flange or foot type, fixed version or with axial adjustment (+/-25 mm), with fixed or sliding journal. The safety chuck closes automatically with the rotation of the shaft and it can only be opened in vertical position.

The standard versions for square journal ends 30×30 / 40×40 / 50×50 mm have reduced dimensions and are economical. Available as flange or foot mounted versions in “light” or “heavy duty” executions.

The range of models actually on the market includes safety chucks mod. AVR-101, AVR-102, AVR-103, divided in the following versions:

AVR-101/102/103: self-locking safety chucks fixed version;
AVR-101/102/103-RV: self-locking safety chucks with axial adjustment, hand wheel side;
AVR-101/102/103-RM: self-locking safety chucks with axial adjustment, drive side (sliding end journal);
AVR-101/102/103-RMF: self-locking safety chucks with axial adjustment, drive side (fixed end journal);

Unidirectional friction Shaft with Double Row of Expanding


Fast and simple cores loading and positioning
Centered cores on friction rings and held firmly in place until each reel is fully wound
No spacers required
Slipping occurs inside the shaft so no core dust is created
Opportunity of interchanging friction rings for different diameter cores on the same shaft
Suitable for carton and PVC cores
Excellent friction sensitivity
Opportunity of rewinding multiple slit reels with variable widths on one shaft
Simple reel releasing and removal for rapid changeovers eliminating costly down-time
Easy substitution of expanding friction key rows on carrier shaft
Delivery terms 4/6 weeks


Hard chromium-plated ground steel carrier shaft
Dynamically balanced expanding carrier shaft3″ and 6″ friction rings using the same central shaft
Available for cores diameter since 50 mm to 300 mm
Minimum reel width 7 mm for 3” cores
Exclusive interchangeable friction key rows that, in contact with friction rings, transmit the required torque to individual reels to ensure an uniform winding
Axial or radial inflating
Opportunity of retrofitting on existing machines
Custom made steel journals to suit any machinery
Opportunity of radial inflating through special rotating joints of I.E.S. production (steel or aluminium execution)

Particularly indicated for the rewinding of reels of materials with different thicknesses over the width of the web maintaining at the same time an equal tension as in the case of multiple slit reels. Recommended for use on slitting and rewinding machines, this friction shaft ensures from the first runs an equal and uniform winding of each single reel, even the narrowest webs. The friction force is regulated, when the machine is running, by a continuous air supply at a pressure ranging from 0 to 6 bar through a rotating joint connected to the axis of the shaft. This pressure allows the special keys to expand against the friction elements positioned along the carrier shaft and therefore transmits the necessary torque to the individual reels to ensure a uniform winding. A simple turn of the cores on the friction element provides a firm radial and axial grip eliminating the need for any spacers.

Self-Expanding Mechanical Chucks CLEV12-TBA with Adaptors

Self-centering and self-expanding mechanical chucks based on the same principle of operation of the new CLEV12 mechanical shaft, these chucks satisfy the same functions of the most common pneumatic or pneumechanical chucks with the difference that now is unnecessary compressed air as well as the using of inflating or deflating devices.

Core locking happens by radial expansion of a steel balls set moved thanks to an outer sleeve with a drag function, these balls generate a pressure and then a torque on the inner core surface engaged on the shaft. Transmitted torque is unlimited, its value depends only by the quality of the core.

Depending from operational needs, adapters for several size of core diameters, from 3” up to 12” are rapidly mounted on the standard chuck body.

About us

Company details


Since 1965 I.E.S. Srl is at the service of the printing, paper and converting industries with the in-house production and sale of technologically advanced expanding air shafts appreciated in Italy and all over the world for their high quality standard.

Their exclusive design and operational features, patented world-wide, distinguish them from all the others present on the market.

From the very beginning our primary objective has been to provide shafts that are extremely reliable though being very light.

Thanks to our constant research and development we are able to manufacture expanding air shafts at very competitive prices and satisfy varied customer requirements: from common standard shafts to the most complicated projects.

For the manufacture of our products our factory relies on the precision provided by modern high technology CNC machinery and the expertise of qualified technicians.

I.E.S. Srl means seriousness, competence, quality, innovation at competitive prices.
