Boston Gear FC15-7/8 Flexible Shaft Coupling

The FC15-7/8 from Boston Gear (Regal Rexnord) is a steel, 3-jaw jaw coupling hub (FC Series) that connects two rotating shafts in industrial power transmission, providing misalignment compensation and vibration dampening while transmitting torque. It uses a 7/8 in bore (FC15 size), with a 1.50 in outside diameter and a torque capacity up to approximately 500 in-lb (insert dependent) at speeds up to 1750 RPM; full assembly requires an elastomer insert. Mounting is by set screw or keyed shaft connection. Common applications include conveyor drives, pumps, gearmotor assemblies, packaging equipment, mixers, fans, and other general mechanical drive systems where a flexible shaft connection maintains smooth power transmission between motor and load.
