The standard output shaft is the optical axis, which can be milled into single flat or double flat according to user requirements. If a keyway needs to be customized, the shaft diameter can be changed to 8mm. The standard length of the rear output shaft of the double output shaft motor is 15mm, and for stepper motors with special requirements, the maximum shaft diameter can be 9.5mm.
