Specifications
- Core diameter ranges from 45 mm to 300 mm.
- Roller diameter ranges from 3.2 mm to 8 mm.
- Minimum air pressure required is 6 bar.
- Friction rings are available with a minimum width of 4.5 mm.
Procedures and Features
- Friction shafts with rollers provide a wide supporting surface, ensuring greater stability of the roll core by keeping it perpendicular to the central shaft.
- Expanding rollers allow for safe and easy roll removal without damaging the cores, enabling their reuse.
- Friction rings with rollers are made of hard black anodized aluminum or steel, equipped with expanding rollers for optimal performance.
- Preloaded positioners can be added to friction rings starting at 19.65 mm width to center and stabilize the reel cores during machine startup.
Friction Shafts with Balls
- Designed to avoid damage to reel cores during unloading by having balls under the outer surface of the ring.
- Made of hard black anodized aluminum or steel, with an inner bearing of spheres for increased sturdiness and fluid sliding action.
- Preloaded positioners are available for friction rings starting at 12.15 mm width.
Special Applications
- Various configurations of expanding shafts and safety chucks are available, including cantilevered expanding shafts and flange safety chucks with axial movement.
- Pneumatic brakes such as the Extreme XT.7 and CX.250 are used in conjunction with these systems.
