3mm Bore 32 Pitch, 12T Shaft Mount Pinion Gear

This 12 tooth, 32 pitch pinion gear fits perfectly on 3mm round and 3mm D-profile shafting, such as found on our N20 line of gear motors. The 6-32 cupped point set-screw will fix the pinion onto the shaft and hold it from spinning or moving axially. While this gear will mesh with any tooth count of 32 pitch, 20 degree pressure angle gear, it’s most commonly used with an 84 tooth hub gear spaced 1.5” apart to create a 7:1 gear reduction.
