Boston Gear FC15-3/4 is a 3/4-inch bore steel jaw coupling hub in the FC series, machined from alloy steel for strength and durability. This straight-jaw coupling half (FC15-3/4) has a 0.75 in bore and is finished with a keyway and set screws for secure shaft attachment. As a coupling half, it pairs with the matching FC-series half to form a jaw coupling used for transmitting torque between shafts while accommodating minor misalignment in industrial drives.
