Dear everyone, this reciprocating mechanism is just a semi-final product (as shown in the picture) and does not include the motor power source. If you need a power source for the motor, you can contact customer service to purchase it. The reciprocating mechanism depends on an integrated extended slider strip, which is more stable. I noticed most reduction motors have an 8 mm output shaft, so the motor mounting hole on the oscillating arm is virtually 8 mm. If you need other specifications, please contact customer service. Below are the final products for the store owner. Please refer to them. If you need them, please contact customer service! (This link does not include the motors!)
