Browning 3P3V53 3-Groove Sheave

Browning 3P3V53 is a 3-groove V-belt pulley designed for 3V/3VX belts, cast in close-grain cast iron for precise tolerances and smooth, vibration-free operation. It uses a split-taper bore (P1 bushing series) and requires a Browning split-taper bushing for a true Key‑to‑Key drive to shaft and hub. The pulley measures 5.3 inches outside diameter, with a 5.25-inch pitch diameter and a 1.5-inch face width, and an overall length of 2 3/16 inches. It is a 3-groove configuration intended to distribute belt load across all grooves, improving belt life and drive stability. The bore accommodates a range from 1/2 to 1-3/4 inches and features a 3/8-inch keyway for secure shaft engagement, with a weight around 6 pounds. Engineered as a static-balanced component, it is compatible with Gripbelt 3V cross-section belts and is suitable for standard belt-driven applications where a compact, multi-groove pulley is required. Browning emphasizes close-tolerance machining on these sheaves to ensure consistent belt alignment and performance across installations, making 3P3V53 a reliable choice for 3V-drive systems that demand repeatable, long-term operation.
