This adapter converts an 8 mm keyed shaft to 1/2 in. hex. The keyway is 2 mm wide. This allows you to adapt the output of a motor or gearbox like the CIM Motor (am-0255) to any of our hubs or wheels with a 1/2 in. hex bore. You'll need a 2 mm machine key (am-1121) to complete the assembly and transmit torque from the motor.
This adapter is no longer available in the 0.75 in. length.
