Boston Gear FC30 1 1 4 CPLG 08286 Flexible Coupling

Boston Gear FC30 1-1/4 in Bore Half Hub (catalog 08286) is the FC30 jaw-coupling half designed to pair with the matching FC30 insert to form a two-piece flexible drive connection. This straight-jaw half is built in steel and features a 1-1/4 in bore with a keyway for secure shaft mounting. As part of the FC30 family, it is intended to be used with the corresponding FC30 coupling insert to transmit torque while accommodating minor misalignment and reducing vibration in compact power-transmission setups. Common applications include small-motor drives, gearmotors, and light machinery where space is at a premium and a resilient, precisely aligned connection is required. The 08286 variant identifies this specific half-hub in Boston Gear's FC30 lineup, ensuring compatibility with standard FC30 inserts and other FC30 half-hubs for assembled couplings.
