Industrial Powertork Size 2-1 2F Gear Coupling Flex Hub 2-3 4in Bore Gear Coupling

The Industrial Powertork Size 2-1 2F flex hub gear coupling with a 2-3/4 in bore is a heavy‑duty shaft-mounted gear coupling hub designed to transmit torque between rotating shafts while compensating for angular and parallel misalignment. It features a 10-bolt flange with an outside diameter of 8-3/8 in, a 0.78 in keyway, and heavy‑duty steel construction, weighing about 19 lb. This gear coupling is used in pumps, compressors, conveyors, mixers, and other industrial drive equipment, and is commonly installed by maintenance teams and system integrators for repair, retrofit, expansion, and replacement in industrial power transmission systems.
