Helical 550 Motor Pinion Gear - 12 Tooth - 2 Pack

The 550 Motor Pinions are used for transferring power from a 550 class motor, like the HD Hex Motor or NEO 550, to a mechanism. The Helical 550 Motor Pinion with 12 teeth is used exclusively with 20:1 and 40:1 Hex gearboxes ONLY (REV-41-1064 and REV-41-1065 respectively).

The pinions are press fit onto 0.125in motor output shafts. Using a small drop of retaining compound, such as Loctite 609, ensures a snug fit.
