Our SPB series v-belt pulleys are high-performance power transmission components designed for a wide range of industrial applications, including motors, compressors, pumps, conveyors, machine tools, agricultural machinery, and mining equipment. Covering SPB3, SPB4, SPB5 models with pitch diameters from 120mm to 200mm, this full series meets diverse load and speed requirements for different mechanical systems.
Manufactured from premium grade cast iron, these pulleys deliver superior strength, rigidity, and wear resistance, ensuring stable operation under heavy loads and continuous working conditions. The precision-machined SPB grooves perfectly match standard SPB 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 (blue/green) for enhanced rust protection in harsh environments. We support custom bore sizes, non-standard keyways, and special surface treatments to meet specific application requirements, with large inventory to ensure fast delivery worldwide.
