Chicago Die Casting 500A6 V-Groove Die-Cast Pulley 5'' in Dia.x 5/8'' in Bore ? Zinc Ensure smooth and reliable power transmission with the Chicago Die Casting 500A6 V-Groove die-cast pulley, a precision-engineered single groove pulley designed for industrial and mechanical applications. With a 5-inch outside diameter and a 5/8-inch bore, this Type A pulley is built to fit standard shafts and is optimized for use with 4L (1/2 in W x 11/32 in thick) V-belts, making it ideal for a wide range of belt-driven systems including motors, pumps, blowers, and agricultural equipment. Constructed from high-strength zinc via die-casting, the pulley delivers excellent durability, dimensional stability, and resistance to wear and corrosion. Its V-groove design securely guides the belt, minimizing slippage and ensuring efficient power transfer. The pitch diameter of 4-3/4 inches and a face width of 11/16 inch are engineered for optimal belt alignment and performance. The 3/16 x 3/32 inch keyway ensures a secure fit on the shaft, preventing rotation and reducing wear on both the pulley and drive system. Equipped with hollow head set screws (included), the pulley allows for precise mounting and secure attachment without the need for additional hardware. These slotted, headless screws provide a flush finish and reduce the risk of snagging, making them ideal for enclosed or high-safety environments. The pulley is designed for use with A-series belts, and models from 2 to 12 inches in diameter include keyways?except for 3/8 in and 1/2 in bores, and 3/4 in bores on pulleys under 4 inches. Measuring 5.20 inches in length, 1-7/32 inches in width, and 1.30 inches in height, this compact yet robust pulley is lightweight at 0.800 lb, facilitating easy handling and installation. It is packaged in a Sta-Pak carton for protection and retail readiness.
