V-Belt Pulley
Flexible V-Belt Pulley Options for Various Industries
V-belt pulleys feature a unique V-shaped groove design that provides enhanced grip, ensuring reliable power transmission and minimizing slippage even under heavy loads.
Flexiparts specializes in custom V-belt pulleys, offering tailored solutions for size, material, and precision. We utilize injection molding for thermoplastics and compression molding for thermoset or composite materials, ensuring durability, accuracy, and cost efficiency. Please send us your 3D drawings for a custom quote.

Custom V-Belt Pulleys Made to Your Specifications
We do not offer standard catalog sizes. Each V-belt pulley is manufactured to your drawing, sample, or belt specification to match the required belt profile, shaft connection, and application.
Typical customization options include:
- Groove Profile: A, B, C, SPZ, SPA, or custom profiles
- Outer Diameter: Manufactured to your specified dimensions
- Groove Count: Single, double, or multi-groove
- Bore and Hub: Plain bore, keyway, set screw, metal insert, or press-fit bearing
- Dimensional Tolerances: Controlled to your drawing requirements
Not sure which specifications are required? Send us your belt model, drawing, sample, or application details. We can review the requirements and confirm the pulley design before production.
FAQ About V-Belt Pulley
1. Should I choose a V-belt pulley or a timing pulley?
Choose a V-belt pulley when you need strong friction grip and some tolerance for belt stretch or slight misalignment. Choose timing pulleys when the shafts must stay exactly synchronized and no slip is acceptable. If you are not sure, send us your application details and we can suggest the better fit.
2. What is the difference between a sheave and a pulley?
In everyday use the two terms overlap. A sheave usually refers to the grooved wheel itself, while a pulley often means the complete wheel-and-shaft assembly. Our guide on sheaves vs. pulleys explains where the terms differ and when each is used.
3. Which plastic material is best for a V-belt pulley?
It depends on load, speed and environment. Nylon is a common all-round choice for wear resistance, while POM suits tighter tolerances and quieter running. See our nylon pulleys page for material details, or tell us your operating conditions and we will recommend a grade.
4. Can you add a metal insert or bearing to the pulley?
Yes. We can mold in metal inserts or press-fit bearings for higher loads. See our plastic bearing pulleys for examples.
