Browning AK56x5 Sheave

Browning AK56X5/8 is a finished-bore, single-groove cast-iron V-belt pulley designed for 3L, 4L, or A-section belts with a 5/8 in bore and a 5.45 in outside diameter. This Browning pulley features a statically balanced, spoked construction with a finished bore and a 0.1875 in keyway, enabling smooth operation in fractional horsepower belt drives. Core measurements include a 5/8 in bore, 1 groove, outside diameter of 5.4500 in, face width of 0.7500 in, and an overall width of 1.2188 in, plus a hub length of 1.1563 in. For belt sizing, the pitch diameter is 5.4000 in (A section) and the datum diameter is 4.8600 in (3L) or 5.2000 in (A), helping ensure proper fit in the drive train. Weighing about 2.63 lb and made from close-grain cast iron, the AK56X5/8 carries a finished bore and does not require a separate bushing in standard setups. This pulley is intended for Browning belt-drive systems and is commonly used to transmit power to auxiliary or driven components where a compact, reliable single-groove solution is needed.
