In power transmission systems where torque, load capacity, and belt tracking are critical, V belt drive pulleys offer a reliable and efficient solution. Triangle Machine Products manufactures precision V belt drive pulleys across a wide range of industrial applications. From compact drive systems to heavy-duty machinery, our V belt pulleys are custom-machined to deliver dependable power transmission in even the most demanding environments.
Whether you’re working with a classic single-groove V belt or a modern multi-ribbed poly V configuration, our machined pulleys ensure your system performs at peak efficiency. Designed for tight tolerances, Triangle’s pulleys support reduced vibration, improved belt wear, and enhanced mechanical performance across the life of the equipment.
V belt drive pulleys must maintain precise groove geometry, balanced rotation, and optimal surface finishes to support consistent power transfer. At Triangle Machine Products, we machine each pulley to exacting specifications, ensuring accurate belt fitment and alignment under dynamic loading. Our pulleys are suitable for a variety of systems, including HVAC units, material handling equipment, agricultural machinery, compressors, and industrial automation.
Unlike cast or stamped alternatives, our machined V belt pulleys exhibit superior balance and concentricity—reducing wear on belts, shafts, and bearings. This level of performance is especially important in systems that operate continuously or under fluctuating load conditions. We manufacture both conventional V belt pulleys and poly V pulleys (also known as micro-V or serpentine pulleys) to match your specific drive requirements.
Triangle Machine Products offers custom V belt pulley solutions to meet the distinct needs of each customer. Whether you require a standard profile or a specialty configuration, we can accommodate your project’s specifications—from prototype development through full-scale production.
Custom machining options include various groove profiles (A, B, C, D, E, or custom poly V), bore dimensions, keyways, set screw features, and hub styles. We also offer custom pulley balancing and secondary operations such as plating, coating, or engraving to support your application’s technical and branding requirements. Our ability to hold tight tolerances—beyond what casting or forming methods can achieve—ensures your pulleys perform reliably in high-speed, high-efficiency systems.
With a proven track record of manufacturing critical rotating components, Triangle Machine Products brings unmatched machining expertise to the production of V belt drive pulleys. Our CNC equipment, quality control protocols, and customer-first approach ensure that every pulley meets your design intent, performance expectations, and delivery timeline.
We work with engineers and procurement teams across a range of sectors—including industrial automation, transportation, food processing, and OEM equipment—who rely on us for precision components that standard suppliers can’t deliver. If your application demands custom geometries, tight tolerances, or enhanced durability, Triangle is the manufacturing partner you can count on for premium results.
Standard V belt drive pulleys typically feature a single or multiple classic V-grooves, designed for traditional wedge-style belts. Poly V pulleys, by contrast, feature multiple small ribs that increase surface contact, reduce slippage, and improve efficiency in high-speed applications.
Yes. Triangle specializes in custom V belt and poly V pulley machining, tailored to your exact specifications for size, profile, bore configuration, and material.
We offer pulleys in aluminum, steel, stainless steel, and specialty alloys. Available finishes include black oxide, zinc plating, anodizing, and custom coatings to support corrosion resistance and performance.
