64 Pitch 56 Tooth Pinion Gear

Our line of ultra precise pinion gears, machined perfectly round, are drilled and tapped to accept the 5-40 set screw. Each part is stamped with the tooth number for easy identification. The pinions are constructed from aircraft grade light 6061 aluminum with a hard teflon coat, black anodize. Eight additional &quot;lightening&quot; holes have been added to reduce the rotating mass (of applicable sized pinions). They will fit any motor with a 1/8 motor shaft. No messing with the normal 0.050 allen wrench, these take the large 0.062 tip wrench that are used on your 4/40 button head screws.<br /> <br /> Sizes are available from 15 tooth to 60 tooth, in 64 pitch.
