Triangle Machine Products manufactures high-quality machined fan hubs built for long-term performance in high-speed, high-demand industrial environments. These components serve as the central connection between rotating shafts and fan blades—requiring tight tolerances, reliable balance, and structural strength to operate safely and efficiently under dynamic conditions.
Unlike stamped or cast hubs, Triangle’s industrial fan hubs are precision-machined from bar stock, allowing for superior control over fit, concentricity, and surface finish. Whether you need custom bore dimensions, bolt hole configurations, or keyed features, we provide solutions that integrate seamlessly into your rotating assemblies.
Fan hubs are critical components in ventilation, cooling, and air handling systems. They serve as the load-bearing center of axial fans, impellers, or multi-blade rotors, and must maintain consistent rotation with minimal vibration or imbalance. Triangle specializes in machining fan hubs to exact specifications, ensuring that every hub meets the dimensional integrity required to support balanced motion and reliable power transfer.
Our machining services support both prototyping and high-volume production. Using multi-axis CNC turning and milling centers, we can produce hubs with complex features such as tapered bores, bolt hole patterns, keyways, threaded inserts, and integrated flanges. Every part is produced with tight concentricity and runout control to help maintain proper fan alignment and minimize noise and wear in service.
Each fan application has its own mechanical and environmental requirements—and Triangle Machine Products is equipped to meet them. We manufacture custom fan hubs for applications ranging from HVAC systems to large-scale cooling towers, industrial blowers, and heat exchangers. Whether your assembly demands corrosion resistance, specific dynamic balancing tolerances, or precision mating surfaces, we deliver hubs that perform reliably in the field.
We work directly from your CAD models or engineering drawings and can assist in refining dimensions for manufacturability. From custom mounting configurations to unique shaft fits or pilot diameters, our team ensures that every hub is optimized for strength, alignment, and installation consistency. Our hubs are machined from raw materials such as carbon steel, stainless steel, and aluminum alloys, depending on your operating environment and performance goals.
Precision matters when it comes to rotating equipment. A poorly machined hub can lead to misalignment, vibration, premature bearing wear, or even catastrophic failure. At Triangle Machine Products, we approach every fan hub with the same commitment to dimensional control and performance reliability we bring to all high-spec machined components.
With decades of experience in precision turning, milling, and balancing-critical parts, we produce hubs that meet your specifications and support smooth operation over time. Our machining capabilities allow us to consistently hold tolerances that casting or forming processes struggle to match—making Triangle the ideal partner for applications where precision is a requirement, not a luxury. Whether you’re building industrial fans, heat exchangers, or air handling units, Triangle’s fan hubs deliver repeatable results across every order.
A machined fan hub is a precision component used to connect fan blades to a rotating shaft in equipment such as HVAC systems, cooling towers, industrial blowers, and compressors. It ensures alignment and structural integrity during high-speed rotation.
Yes. We manufacture custom fan hubs with features such as tapered or straight bores, bolt hole patterns, flanges, keyways, and other machined details to suit your design requirements and performance needs.
We offer a range of materials including carbon steel, stainless steel, aluminum, and specialty alloys based on the required strength, corrosion resistance, and thermal environment of the fan assembly.
