4mm Bore 32 Pitch, 16T Shaft Mount Pinion Gear

This 16 tooth, 32 pitch pinion gear is a slip-fit on a 4mm shaft. The 10-32 cupped point set-screw will fix the gear 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 80 tooth hub gear spaced 1.5” apart to create a 5:1 gear reduction.
