Serpent SER120122 Precision 64P/35T Aluminium Pinion Gear  [SER120122]

Serpent SER120122 aluminium pinion for controlled power delivery

The Serpent SER120122 Motor-pinion is a hard aluminium 64P/35T gear engineered to transfer motor torque efficiently to the spur gear. It is a practical upgrade for builders wanting to stabilise gear engagement and reduce unwanted play.

Robust aluminium construction for repeatable runs

Constructed from durable aluminium to keep tooth profiles accurate under stress, the pinion helps maintain consistent gear mesh. The 64 pitch with 35 teeth helps you tune acceleration and top speed for different track surfaces.

Quick installation and reliable fit

Fitting this pinion only needs standard hobby tools and a careful mesh check. Always confirm shaft dimensions before fitting to prevent slippage or binding and retest mesh after the first short run.
