What is a Multi-V Nylon Pulley?

• A Multi-V Nylon Pulley is also known as a Multi-Grooved Pulley or Multi Rib Pulley
• This nylon pulley features multiple V-shaped grooves or channels on the pulley face, hence the name "Multi-V."
• The V-shaped grooves provide increased surface area for the belt to contact the pulley.
• Allowing the belt to sit securely and transmit rotational force efficiently, minimizing slippage and maximizing power transfer.
• Proper tension is crucial for the performance and longevity of the Multi-V belt.

Design and Construction of Multi‑V Nylon Pulleys

Precision‑engineered multi‑V nylon pulleys deliver efficient, dependable performance across industrial applications. Exact diameter and width specifications ensure smooth belt alignment, torque accuracy, and optimized power transmission throughout mechanical systems.

Engineered Strength and Efficiency

Nylon offers a proven balance of strength, lightweight design, and resistance to wear, oils, and chemicals. Its low mass reduces inertia and energy consumption while simplifying installation and handling—ideal for demanding environments like food processing and automation.

Configurable for Any Application

Available in multiple diameters and groove configurations, multi‑V nylon pulleys provide flexibility to match performance needs. Whether used with flat, multi‑V, or specialty belts, they maintain alignment, minimize friction, and extend service life under continuous load.

Reliable, Cost‑Effective Solutions

Durable nylon construction reduces maintenance and operating costs while ensuring long‑term reliability. Partnering with a trusted manufacturer secures accurate sizing, prompt delivery, and optimal pulley performance for both new builds and replacements.What are the Advantages?

Run on smaller diameter pulleys
Transmit high torque loads at high speeds.
Run quietly without vibration.
The more compact the design and lighter the weight of drive components, the lower the drive inertia
Torque Transmission specializes in custom pulley systems tailored to specific requirements, offering a wide range of configurations to meet unique operational needs.

Multi-V Nylon Pulley - What is the Value?

• For OEM applications using an H, J, or K pitch
• Molded Nylon 6/12 has a tensile strength of 22,000 psi, able to handle shock loads, high speed, and continuous use.
• Nylon is an engineered, 33% glass-reinforced material, offering many advantages over other pulley materials. Nylon is half the weight of aluminum and one-seventh the weight of steel. Less inertia (less weight) means quicker starts, stops, and reverse actions.
• Multi V nylon pulleys cost, on average, 25-50% less than aluminum pulleys in volume quantities.
