This aluminium ULTRA-LIGHT pinion is a dedicated RC-scale motor pinion engineered for low rotating mass while retaining strength through a hard coated 7075 T6 aluminium construction. The gear is machined on a specialised gear machine to achieve precise tooth profiles and true running, which reduces vibration in the drivetrain when paired with a matching spur gear.
Design details focus on practical serviceability for hobby use: fine internal threading for straightforward mounting, clear tooth-count etching for quick identification, and a hard coating to increase wear resistance without adding significant weight. The product name includes the working spec "20T / 64" to indicate the tooth count and pitch reference used in selection and matching.
In tuning terms, this pinion is intended where reducing motor inertia is required to improve throttle response and minimize rotating losses, while still maintaining the dimensional stability needed 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 reliable tooth geometry are priorities.
