This 40 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 able to be meshed with a 80 tooth hub gear spaced 48mm away for a 2:1 ratio, or, it can mate to a 20 tooth gear to create a very compact 2:1 ratio only 24mm apart! 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. Notice the counterbore on the top side of the gear - this allows you to run right up against an 8mm bearing without the use of a shim!
