Carbon fiber rollers arewidelyused in print, film, paper, and liquid crystal displays industries. In recent years,with the increase in size (width) and speed of manufacturingsystems,carbonfiberroller demand is growing. The carbon fiber tubeshell produced in the form ofrollwrapped method using prepreg carbon fiber fabric as raw materials, are more popular. We can provide different designs and coatings that meet customer needs.
Here are the rollers type we are manufacturing:
| Accumulator rollers | Conveyor rollers | Lay on rollers | Pinch rollers |
| Air shafts | Dancer roller | Load cell rollers | Pull rollers |
| Calendar rollers | Guide rollers | News printing rollers | Reel spools |
| Conical sleeves | Idler rollers | Nip rollers | Roll cores |
| Contact rollers | Impression rollers | Parallel sleeves | Tension rollers |
Features
1.Lighter weight & high strength: Improved safety.
Roll replacement workability greatly improves, contributing to improved safety.
2.Lower inertia: Reduced running costs.
Stable transport is achieved with thin material and low tensile force, and reduced drive energy helps reduce cost.
3.Low deflection: Improved product quality
Stable base material transport improves product quality.
4.High RPM: Improved productivity.
While high rotational control is maintained, the critical speed is increased.
5.Higher load capacity than comparable aluminum idlers
6.Non-corrosive and longer lifetime.
7.Electrically conductive.

-Φ100×1700L, same rigidity
The strength and lightweight of carbon fiber idler rollers offer unparalleled quality – weighing only one-third of standard aluminum idler rollers of the same class, but with stronger load bearing capacity. These high-performance idler rollers use a carbon fiber composite tube as the roller shell. Special steel short shafts and lightweight aluminum collecting tubes minimize the total weight of the roller.
These exceptional idler rollers are ideal for running wider and lighter rolls at higher critical speeds. Their inertiagrade is the lowest among all the cylinders in the market. Most importantly, you can now specify them as the “future” standard – saving you the cost of customizing carbon composite idler rollers.
Comparative Example of Metal Roll and Carbon Roll
The performance of carbon rolls varies according to the design.
For example, the performance of a metal roll and carbon roll of the same size and rigidity iscompared below.
