Other reminders:
1...If an integrated worm shaft is used with a turbine with a speed ratio of 20-70, the center distance should be added 0.3mm to the above data (because the radius of the worm shaft is 0.3mm larger than the radius of the worm with holes)
2...Please keep 0.06-0.08mm side clearance when using and installing.
