Industry standard cross-rigid or cross-stabilized belting design that has lateral rigidity or stiffness for side-to-side support while still allowing the longitudinal flexibility. This is required to mechanically work with the minimum pulley diameters. The cross-rigid design is great for life through deflection wheel bends and for standard idler return on the sidewall tops or with stub idler return idlers. A cross rigid belt has two plies, with the strength yarns running across the belt, one in the top cover and one in the bottom cover (polyester mono-filament or fiberglass depending on the tension demands).
