Description
This SPC3 450-600mm 3-groove v-belt pulley is a high-performance heavy-duty power transmission component, specifically designed for large industrial motors, crushers, compressors, mining equipment, conveyors, and other heavy-load mechanical systems.
Manufactured from premium grade high-strength cast iron, it features a reinforced structure with precision lightening holes, which effectively reduce rotational inertia while maintaining superior strength, rigidity, and load-bearing capacity, ensuring stable operation under extreme heavy loads and continuous working conditions. The 3 precision-machined SPC grooves perfectly match standard SPC section v-belts, minimizing belt slippage, reducing energy loss, and extending belt service life.
Each pulley is equipped with a standard bore with keyway and set screw hole for easy installation and secure locking on the motor shaft. Available in raw cast iron finish, or with anti-corrosion painting for enhanced rust protection in harsh environments. This series covers 450mm, 500mm, 550mm, 600mm standard pitch diameters, and supports custom bore sizes, keyways, and finishes to meet specific application requirements.
