D Series Industrial Classical V Belt

Classical D Series V-Belts – Maximum Power Transmission for Extreme Industrial Applications

When it comes to the most demanding industrial environments, Classical D Series V-belts are the top choice for high-torque, high-horsepower drive systems. These belts are engineered for heavy-duty applications requiring superior strength, durability, and performance under constant or extreme loads.

With a top width of 1-1/4 inches and a height of 3/4 inch, D Series V-belts provide increased surface contact and enhanced torque-carrying capacity. Their deep, trapezoidal profile ensures reliable grip within pulley grooves, reducing slippage and power loss. Built from premium rubber compounds and reinforced with high-tensile polyester or aramid cords, these belts are designed to resist oil, heat, abrasion, and static electricity.

D Series V-Belt Specifications:

• Top Width: 1-1/4 inch (1.25")

• Height: 3/4 inch (0.75")

• Pitch Length: Approximately 5.0 inches shorter than outside length

• Typical Lengths: 90" to over 500"

• Construction: Fabric-wrapped for durability, oil/heat resistant, static conductive

Common Applications:

• Rock crushers and mining equipment

• Industrial mixers and grinding mills

• Heavy-duty compressors and HVAC systems

• Forestry and lumber processing machines

• Agricultural combines and industrial tillers

• High-capacity conveyors and fan systems

D Series V-belts are built for rugged performance in environments where downtime is not an option. Their thick profile and heavy-duty construction make them ideal for transmitting large amounts of power over long center distances.
