Ultralight and super-fast, Svecom’s carbon fiber shafts allow for wide spacing in design geometry and meeting of all customer needs. Our experience in the use of this material dates back to the early 1990s, and the collaboration that took place in the United States between our sister company Goldenrod Corp. and Lincoln Composite. After years of studies, patents and checks on product quality and the achievement of our goals, in 2020 we produced the first fully expanding, carbon fiber shaft.

This is Svecom’s new patented carbon fiber shaft with three ledges, which is a true innovation and revolution in the industry. Thanks to the exclusive use of carbon, the mechanical characteristics and performance have surpassed and improved all past achievements:

  • Greater strength, thanks to the 250Gpa elastic modulus
  • Greater lightness compared to other solutions. It is estimated to be 65% lighter than steel shafts, 15% lighter than aluminum ones and a good 37% compared to carbon shafts with steel inserts
  • Dramatic decrease in the time to reach maximum machine speed due to lower weight and high elastic modulus
  • Faster acceleration, up to 5/6 times better than standard shafts
  • Increased critical speeds, +80% increase over steel models, +19 over aluminum shafts, and a +39% increase over combined carbon and steel insert shafts.

What are carbon fiber shafts and what are they used for?

This particular type of shaft is placed in coil winding or unwinding machines: the coil is placed on them so that the coil can be wound or unwound. Commercially available pneumatic expanding shafts are generally very heavy, and in addition there are different shapes, models and lengths, containing different sections as well.

Svecom’s patent for an ultralight and fast carbon fiber shaft

Understanding the difficulties of heavy and unsafe machinery for workers, Svecom has filed a patent to make shafts from carbon fiber, which are very light, extremely high-performing and durable.


This product is made with features that allow an improvement in performance, both in terms of light weight and speed. The use of this machinery is suitable for winding and unwinding coils with cores, and the standard features listed are all fully customizable to customer needs:

  • high-strength rubber tubes
  • various pin materials available
  • quality components
  • wide selection of expanding elements


This Svecom model was created in cooperation with our U.S. subsidiary Goldenrod Corporation, and is patented as an extremely rigid, lightweight, and easy-to-handle shaft.

The “Pultrusion” model is particularly suitable for applications that exceed the yield strength limit of aluminum, and in all cases where steel or conventional carbon fiber shafts cannot be used.

The features of these particular carbon coil shafts are:

  • Multiple air chamber system
  • Excellent centering
  • High-strength rubber tubes
  • Various pin and body materials available
  • Quality components
  • Wide selection of expanding elements.

Our range sections:


Used for unwinding reels on tangential belts unwinding machines, non-expanding chucks have a lightweight design in the chuck, allowing for better manual handling while avoiding automated lifting systems.

The steel neck cover allows the use of overhead crane hooks, the chuck is without replaceable welds or inserts, and the attachment in the machine is made at the customer’s request.


The range of available solutions is wide, as each roller can be customized with dedicated surface treatments.

The reference dimensions are as follows:

  • Maximum diameter of 400 mm
  • Maximum length of 6,000 mm

It is understood that Svecom-P.E. is fully available to develop new solutions in cooperation with the customer, because making customized products has always been the distinguishing feature of the supply.

The production process of carbon fiber rollers

The process includes a dedicated production plant in which rollers of different sizes can be processed according to customer requirements.

Svecom-P.E. is able to manufacture the rollers with both technologies currently available in the market, namely:

  • Filament Winding
  • Roll-Wrapping

Over the years, investments in research and development on these production techniques have been considerable, in order to be able to constantly improve efficiency and performance in terms of thermal stability, weight, high critical speeds, stiffness, lower vibrations, mass reduction, and last but not least, corrosion resistance.
