Notched belts in polyurethane XL – H as well as the HTD with metallic insert are used in low power transmission where products with limited tolerance are required (for example: horizontal and vertical automatic doors). Their main characteristics are as follow: resistance to friction and oil, uniformity of profile (Thickness, positioning of metal insert, notch shape), good flexibility.
