A&I B43K Premium Kevlar V-Belt - 5/8" Top Width, 46" Outside Circumference Excellent performance for drives having clutching applications and backside idler drives Provides reduced slippage while clutching Able to withstand high level of reverse flexing Superior resistance to oil, heat, cracking, ozone sunlight and weather

The 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 Kevlar belts to have a high resistance to repeated reverse flexing, oil, heat and cracking. Kevlar belts also offer high tensile strength, non-extensibility, and high resistance to shock loads.
