Custom cast iron pulley
Our custom cast iron pulleys are sand-cast and precision-machined for industrial power transmission, agricultural machinery, and decorative architectural applications. Available in V-belt, flat belt, and multi-groove configurations, each pulley is machined to your exact bore diameter, keyway specification, and outer diameter. The wall-mount bracket version shown is also available for fixed shaft and idler pulley installations. OEM and ODM orders supported with sample production available before mass order commitment.
*Provide your application requirements—such as stress conditions, materials, size range, and even product name. We are always available for customization, so please contact us directly.
Introduction
Why Choose Our Cast Iron Pulleys?
Precision Bore & Keyway Machining — Each pulley hub is CNC-machined to your exact bore and keyway dimensions, ensuring accurate shaft fit and reliable torque transmission with minimal vibration under load.
V-Belt, Flat Belt & Multi-Groove Options — Standard single-groove V-belt pulleys, flat belt pulleys, and multi-groove sheaves all available, with groove profile machined to match your belt cross-section (A, B, C, D, SPA, SPB types).
Integrated Mounting Bracket Available — Wall-mount and flange-mount bracket versions available for idler pulley and fixed-shaft installations, fully customizable in bolt pattern and plate dimensions.
Grey Iron & Ductile Iron Options — Grey iron provides excellent vibration dampening and cost efficiency for standard drive applications, while ductile iron is recommended for high-load and high-speed power transmission systems.
Decorative & Industrial Variants — Our cast iron pulleys are equally suited for vintage industrial interior design, barn door hardware, and decorative wall fixtures, with antique black and aged iron finishes available alongside standard industrial coatings.
