The Browning 2B380SF is a two-groove, QD-bushed V-belt pulley designed for A- or B-section belts, offering a 38.3500 in outside diameter and SF-series bushings to support flexible power transmission in belt-driven machinery. It uses a Quick-Detach (QD) bore with a bore range of 0.500–2.938 in and provides pitch diameters of 37.8 in (A) and 38.3 in (B) while weighing about 64 lb, all cast in close-grain iron for durability. Marketed as an A/B combination drive under Browning’s RRX line and catalogued as AMEC Industrial 2B380SF, this 2-groove pulley is intended to transfer mechanical power across a range of industrial drives and equipment.
