Industrial Flexible Aluminum Shaft Coupling 1-1/2 L 1/2 X 1/4 Bore Shaft Coupling

The Industrial Flexible Aluminum Shaft Coupling connects a 1/2 in shaft to a 1/4 in shaft while tolerating small angular and axial misalignment to reduce vibration in precision motion systems. Made from aluminum alloy, it measures 1-1/2 in long, with an outside diameter of about 1 in (25 mm), and uses a set-screw shaft mount with a flexible/slit-type design to transfer torque while compensating for misalignment. The unit is listed as Generic with model/part number 121212 and is commonly used in CNC machines, servo and stepper motor systems, robotics, CNC routers, 3D printers, and automated equipment.
