Custom CNC Machined Pulleys for Industrial Power Transmission
MetalKeen manufactures custom CNC machined pulleys for industrial power transmission systems, automation equipment, paper machinery, mining equipment, conveyors, packaging machinery, and heavy-duty mechanical systems.
Our pulleys are engineered to provide accurate torque transmission, smooth rotation, excellent balance, and long service life. Manufactured from high-quality steel, stainless steel, aluminum, cast iron, or other customer-specified materials, every pulley is produced using precision CNC turning, milling, drilling, keyway machining, and dynamic balancing.
Whether you require timing belt pulleys, V-belt pulleys, flat belt pulleys, guide pulleys, or completely customized transmission pulleys, MetalKeen provides complete OEM manufacturing according to customer drawings, CAD files, or samples.
With in-house machining, fabrication, engineering support, and quality inspection, we deliver reliable pulley solutions from prototype development to volume production. MetalKeen also supports high-mix, low-volume manufacturing and complete mechanical assemblies.
What Is a CNC Machined Pulley?
A CNC machined pulley is a precision-engineered rotating component that transfers power through belts or cables between shafts. CNC machining ensures accurate groove geometry, concentricity, bore dimensions, and balance, resulting in efficient power transmission, reduced vibration, and longer belt life.
Custom pulleys can be manufactured with various tooth profiles, grooves, keyways, tapers, and hub designs to match specific transmission systems.
