Note that it is not so easy to go in during installation, it is easy to press in, and it will not work!
Calculation method of gear outer diameter: gear diameter = (number of teeth + 2) * modulus
16 parameters: 16 teeth, outer diameter 9MM 5MM thick, aperture 4.97MM
82A parameters: aperture 1.95mm, diameter 5mm, height 5mm
153A parameters: aperture: 2.97mm, gear thickness: 5mm, gear diameter: 8.5mm
143.17A parameters: aperture: 3.12mm, 14 teeth, outer diameter 8MM 5MM thick
122.3A parameters: aperture: 2.24mm, 12 teeth, outer diameter 7MM 5MM thick
92A parameters: aperture 1.95mm, diameter 5.5mm, height 5mm
The above are all 0.5 modulus gears.
71A, 71B are 0.3 modulus, 81A, 91A are other gear parameters of 0.4 modulus, our shop has a separate gear link Our search: copper gear!
The wear resistance of metal gears is much higher than that of plastic gears.
