Pyramid Inc. now manufactures custom-made polyurethane belts in round and flat cross-sectional shapes in a variety of materials with characteristics specifically selected for drive applications, such as those used for conveyor systems. Its Pyrathane 88A product is polyester-based polyurethane with a Shore hardness of approximately 88A. This material has demonstrated a desirable combination of physical properties that make it well-suited as a drive belt.
Pyrathane 88A will provide approximately 30 percent more tension than standard Pyrathane 83A, when applied with the same amount of stretch. Even with the greater hardness and increased tension, this material's flex fatigue resistance is not compromised and is similar to standard Pyrathane 83A. Coefficient of friction is also quite good, as is abrasion resistance.
These belts can be made to either metric or inch requirements, and O-ring cross-sectional diameters are also available in round belts. Round belts can be custom made with cross-sectional diameters from 0.062 inches (1.58mm) through 0.562 inches (14.27mm) with no maximum length restrictions. Flat belts can be made from 0.030 inches (0.76mm) through 0.187 inches (4.75mm) in thickness and in widths up to 1.500 inches (38.1mm) with no maximum length restrictions.
