Classical D Series V-Belts – Maximum Power Transmission for Extreme Industrial Applications
Engineered for High-Torque, High-Horsepower Demands
Classical D Series V-belts are built for the harshest industrial environments, delivering exceptional power transmission for applications that demand extreme torque, high horsepower, and unwavering durability. These heavy-duty belts are designed to operate reliably under continuous loads, shock conditions, and long-span drive configurations where performance and longevity are absolutely critical.
Constructed with premium rubber compounds and reinforced with high-tensile polyester or aramid tensile cords, D Series belts offer superior resistance to heat, oil, abrasion, and static electricity. Their deep, wide trapezoidal profile ensures maximum grip within pulley grooves, minimizing slippage and optimizing energy transfer even under the most strenuous operating conditions.
