MOD 1 Plastic Gears 3.9mm Bore

We have two styles fo these gears, the first from Gears and Sprockets offer great value yet still offer the best possible quality. Colour may vary but typically red. 

The second range are very similar although a slightly different style and also offers a smaller pinion gear of 12 tooth.

Both types of gears have an interference fit 3.9mm hole for a 4mm diameter shaft.
