HUDY 294120 - 20T/64 Hard Coated Aluminium Pinion  [HSP-294120]

Design and machining notes

This aluminium ULTRA-LIGHT pinion is made as an RC motor pinion focused on keeping rotating mass low while maintaining necessary strength via hard coated 7075 T6 aluminium. Machining on a specialised gear machine yields precise tooth geometry and true running, helping to reduce vibration when matched to a compatible spur gear.

Built-for-hobby details include fine internal threading for straightforward mounting, etched tooth-count labelling for quick identification, and a hard coating to improve wear resistance without significantly increasing mass. The working spec "20T / 64" indicates the tooth count and pitch reference used during selection.

As a tuning component, the pinion reduces motor inertia to give crisper throttle response and lower rotating losses while keeping dimensional stability for predictable gear mesh under load.

Opt for this pinion when you want a low-mass, accurately machined 20T / 64 option that prioritises reduced rotating inertia and steady tooth geometry for RC motor installations.
