Browning AK46H Gearbox

Browning AK46H is a cast-iron, single-groove pulley (sheave) from Browning’s AK-series, sized for a 4L belt with a 4.45-inch outside diameter. This AK46H serves as the drive pulley in power-transmission belt systems, providing a rigid, accurately machined surface for V-belts and the durability typical of gray iron pulleys. Bore options for this model include split-taper and bushed configurations to fit Browning hubs, and Browning markets AK46H as part of the AK-Series FHP line of cast-iron bushed sheaves. The 1-groove design accommodates a single V-belt, making it suitable for light- to moderate-torque applications in industrial machinery, conveyors, and packaging equipment where space is limited and belt alignment is critical. Availability across major distributors like Grainger, Applied, Motion, and specialized suppliers confirms its status as a standard replacement component within Browning’s drive-system ecosystem.
