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.

Opciones de Hierro Gris y Hierro Dúctil — 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.
