Boston Gear FC15-7/8 Flexible Shaft Coupling

Description:

The Boston Gear FC15-7/8 Coupling is used in industrial power transmission systems to connect two rotating shafts while accommodating misalignment and transmitting torque. Commonly installed in conveyor drives, pumps, gearmotor assemblies, and general-purpose machinery where reliable torque transfer and vibration dampening are required. Maintenance teams, OEM equipment manufacturers, and system integrators use this coupling for drive system repair, motor-to-load connection, retrofit upgrades, and replacement of worn or failed shaft couplings.

Applications:

The Boston Gear FC15-7/8 coupling is commonly used in industrial machinery such as conveyor systems, packaging equipment, mixers, pumps, fans, and general mechanical drive systems where flexible shaft connection is required to reduce shock loads, accommodate misalignment, and maintain smooth power transmission between motor and driven equipment.
