12.7mm to 0.5 Inch Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections
✔️ Single unit, aluminum, bore 12.7 mm to 0.5 in, 66 mm long
This D40-L66 is a jaw-type flexible coupling designed to connect motors and drives. Made from aluminum, it’s commonly used in CNC machines, robotics, conveyors, and general motor-to-drive applications to transfer torque while tolerating small shaft misalignment and damping twisting vibration. The tight fit provides near-zero backlash at low torque and it includes electrical insulation for safer operation.
