Browning 2BK40X5 V-Belt Pulley

Browning 2BK40X5/8 is a two-groove V-belt pulley designed for Browning BK belt drives. It features a 3.95-inch outside diameter and a finished 5/8-inch bore, providing a compact, precise fit for small-drive applications. Cast in iron, this pulley supports two grooves and is compatible with multiple common belt sections—A, 4L, B, and 5L—allowing flexible power transmission on a single shaft. The BK40 family is built for durable service in standard Browning belt-drive configurations, delivering reliable alignment and load sharing across belts in space-constrained machinery. Ideal for equipment requiring a 2-groove BK pulley with a nominal 4-inch overall diameter and a 5/8-inch bore, this part helps maintain consistent belt timing and drive efficiency in everyday industrial and agricultural applications.
