Currently Sold Out

This 72 tooth hub gear is a popular choice, paired with a 24 tooth pinion gear, to create a 3:1 ratio between holes spaced 1.5” apart.  Alternatively, you can use two 72 tooth gears, on holes spaced 2.25” apart, in order to create a huge 1:1 ratio on counter-rotating shafts.  The ½” bore and 0.77” Actobotics hub pattern means you can attach a hub with the bore of your choice.  The gear has a dished side and a flat side so that you can adjust the position of your gear by flipping it over.
