Made with Kevlar, Blue V-Belt is an extra heavy duty belt constructed of organic polyamide fibers. The polyamide fibers are created by a complex chemical process. This process allows the belts to have a high resistance to repeated reverse flexing, oil, heat and cracking. These belts also offer high tensile strength, non-extensibility, and high resistance to shock loads.     Depth: 5/16"     OC Length: 1/2" X 39"     Top Width: 1/2"
