2303 Series Steel, MOD 0.8 Pinion Gear (8mm REX™ Bore, 20 Tooth)

This 20 tooth 8mm REX™ bore pinion gear is ready to rip!  The bore perfectly matches our 8mm REX™ shafting to create a positive drive.  While little work is left for the set screws, we put two of them in for good measure.  This particular gear is most commonly mated to a 100 tooth hub gear in order to create a 5:1 ratio however if your build provides the freedom to adjust the spacing between your gears, it’s able to mesh to any MOD 0.8 gear that suits your fancy.
