Next-generation keyless gears for flexography
The Duraflex Gear System eliminates the key and the mechanical backlash typical of flexography, ensuring greater registration accuracy, reduced vibration, and improved print quality.
With the Zero Backlash system, applied to printing presses, torque transfer occurs without radial, axial, or reverse torque play, providing stability, repeatability, and interchangeability among different machines.
Key Benefits of the Zero Backlash System
- Registration accuracy at any repeat length;
- Reduction or elimination of gear marks in the print;
- Significant reduction of noise and vibration;
- Elimination of radial, axial, and torque play;
- Intercambialidade total entre impressoras;
- Quick ring gear change with only 3 bolts and a guide pin;
- Simplified pre-registration when coupling to the mandrel or plate mounting cylinder.
