Boston Gear FC 15 3 4” Flexible Coupling Assembly

Boston Gear FC 15 3 4” Flexible Coupling Assembly is a Boston Gear mechanical component designed to join two rotating shafts in a drive system while accommodating slight misalignment and transmitting torque between them. The FC 15 designation places this unit within Boston Gear's FC flexible coupling family, which is used to create a resilient link in mechanical power transmission paths. Flexible couplings like this one help absorb vibration and reduce stress on connected equipment when shafts are not perfectly aligned, ensuring smoother operation and longer bearing life. This assembly offers a compact, robust interface that supports reliable torque transfer across service conditions typical in light- to moderate-load machinery, and it is commonly selected for installations where precise alignment cannot be guaranteed during assembly. As a connection method between rotating components, it serves to preserve system efficiency and protect gears, belts, and motors from alignment-induced wear.
