Knurled surface design: Increases the coefficient of friction, ensuring smooth and reliable roll material operation.
Superior anti-slip performance: Particularly suitable for guiding films, paper, or flexible materials.
Lightweight aluminum structure: Reduces inertial load and supports high-speed operation.
Abrasion and corrosion resistant: Anodizing treatment enhances surface hardness and extends service life.
High-precision concentricity: Ensures flat roll material passage, reducing wrinkles and deviation.
Applications: Widely used in guiding and tension control systems in printing, rewinding, coating, packaging, slitting, and electronic film processing industries.
