Category Name DescriptionSpecifically designed for aggressive applications, this extra heavy-duty belt construction provides extraordinary high impact strength, capacity, and wear resistance.
Features AdvantagesBareback Cover resists debris and allows the belt to slip under extreme shock load conditions, reducing heat buildup and prolonging belt life. Gates Curves provide proper cord support and full contact with the sheave-groove for uniform loading, uniform wear, and increased belt life. Meets ARPM / RMA IP-3-2 oil and heat resistant standards. Aramid Tensile Cords combine limited stretch with extraordinary strength and durability that is pound-for-pound stronger than steel. Multiple layer Tie Band provides excellent lateral rigidity to prevent belts from turning over or from coming off of the drive.
Markets/ApplicationsPredator belts are well suited as replacement belts for applications exposed to pulsating loads or heavy shock loads, such as mining, agriculture, wood processing, oil field equipment, heavy construction and sand/gravel operations.
Size Range/AvailabilityLarge Inventory of standard lengths and widths are readily available. See sizing table for details. Belt Slitters located onsite at several Gates Service Centers can cut down an existing belt in inventory to the strand width needed. Made-To-Order Belt Lengths are available in any size from: CP (80 to 400 inch), 3VP (45 to 220 inch), 5VP (50 to 660 inch) and 8VP (100 to 660 inch).
