Polyurethane Wheels | Adjustable Friction, Ultra-Long Life, Food-Safe Capping Drive Components

Polyurethane wheels are essential for smooth transfer, flexible clamping, and precise positioning in capping machines. Their unique material properties make them irreplaceable in modern high-speed capping applications. They offer superior grip and friction control: coefficient of friction customizable from 0.3 to 0.8—ensuring sufficient torque transmission without slippage or excessive wear on caps. High elastic modulus allows the wheel to conform to various cap curvatures under pressure, delivering uniform contact and preventing deformation or surface scratches. Special textures (e.g., diamond, wave) maintain grip even in wet or oily conditions. Exceptional durability: 5–10x more abrasion-resistant than standard rubber, with a service life of 6–10 million cycles. Highly resistant to tearing and cutting—even against sharp cap edges. Excellent fatigue resistance ensures minimal loss of elasticity after repeated compression and torsion. Additional benefits include oil and chemical resistance, operating temperature range of -30°C to +80°C (higher with specialty formulations), and ozone aging resistance. Available in FDA 21 CFR 177.1680-compliant food-grade grades—non-toxic, low extractables, lubrication-free, and contamination-free. Anti-static versions optional. With their “rigid-yet-flexible” nature—strong enough to transmit power, soft enough to protect products—polyurethane wheels are ideal for high-efficiency, high-quality, low-maintenance capping lines.
