High Strength Large Diameter CFRP rollers with Custom Sizes
Product Overview:
The AstraRoll High-Strength Large Diameter CFRP Roller is a master-engineered solution for wide-web processing in the Paper, Film Converting, and Industrial Packaging sectors. By utilizing high-modulus carbon fiber, these rollers overcome the significant weight and deflection limitations of heavy steel rollers, ensuring perfect material flatness over long spans. This makes them indispensable in the New Energy (Battery foil coating) and Textile industries, where large-scale rollers must maintain precision without sagging or vibration. Our bespoke engineering ensures each roller is custom-sized to fit your specific OEM machinery, providing a lightweight yet incredibly rigid interface for the most sensitive and demanding substrates.
Roll Function: Spreader Roller, Printing Roller, Conveyor Roller, Chill Transfer Rollers

High Strength Large Diameter CFRP rollers with Custom Sizes Details
Exceptional Structural Stiffness: Carbon fiber’s high modulus ensures minimal deflection (bending) even in large diameters and long spans, maintaining a perfectly straight contact surface.
Significant Weight Reduction: At approximately 70-80% lighter than steel, these rollers drastically reduce the load on your machine's motor and bearings, extending equipment lifespan.
Ultra-Low Rotational Inertia: Despite their large size, these rollers allow for rapid acceleration and deceleration, preventing material slippage and tension spikes on high-speed lines.
Superior Vibration Damping: The natural properties of CFRP absorb high-frequency machine harmonics, ensuring stable material tracking at speeds exceeding 800 m/min.
Thermal & Chemical Stability: Maintains exacting tolerances regardless of temperature fluctuations and provides excellent resistance to corrosive industrial solvents.
Key Attributes
Core Material: High-Modulus Carbon Fiber Reinforced Polymer (CFRP).
Shaft Ends: Customizable High-Strength Steel, Stainless Steel, or Lightweight Aluminum.
Surface Options: Mirror Polished, Hard Ceramic, Tungsten Carbide, or PTFE (Teflon).
Concentricity (TIR): Precision-engineered to minimize run-out for consistent material contact.
Balancing Grade: G2.5 High-Speed Dynamic Balancing for vibration-free industrial success.
