HUDY 294120 Aluminium Ultra-Light 20T / 64 Pinion Gear  [HSP-294120]

Lightweight aluminium pinion overview

This aluminium ULTRA-LIGHT pinion is a purpose-built RC motor pinion designed to reduce rotating mass while retaining strength through a hard coated 7075 T6 aluminium construction. The gear is precision machined on a specialised gear machine to achieve accurate tooth profiles and true running, which reduces vibration in the drivetrain when paired with a matching spur gear.

Practical details include fine internal threading for straightforward mounting, etched tooth-count marking for quick spare identification, and a hard coating that increases wear resistance without adding significant weight. The product name includes the working spec "20T / 64" to indicate the tooth count and pitch reference used for selection and matching.

From a tuning perspective, this pinion is intended to lower motor inertia for sharper throttle response and reduced rotating losses while preserving the dimensional stability required for consistent gear mesh under load.

Choose this pinion when you need a lightweight, precisely machined 20T / 64 option for RC car motor setups where reduced rotating weight and consistent tooth geometry are priorities.
