NEO Pinions

The NEO Pinions are used for transferring power from a NEO Brushless Motor or something with a similar matching shaft to a mechanism. These pinions come in three different types; either gear, sprocket, or pulley. The pinion gears are compatible with 20DP gears. The pinion sprocket is used with #25 chain and the pinion pulley is used with GT2 3mm timing belts. These pinions either come compatible with 8mm round shafts with a 2mm keyway or 15T Spline shafts.

The 10, 11, and 12 Tooth Pinion Gears have the same pitch diameter of 0.600in (addendum shifted), meaning that they can be swapped in for each other in an existing design to easily change a gear ratio without any center to center distances changing. The 13 and 14 Tooth Pinion Gears also share the same pitch diameter of 0.700in.
