Hudy Aluminium Hard-Coated Pinion Gear 25T / 48 DY294025

Hudy Aluminium Ultra-Light Pinion Gear - Hard Coated - 25T / 48, part number DY294025, is a 25-tooth, 48-pitch pinion gear for radio-controlled model drivetrains. It is manufactured from 7075 T6 aluminium and receives a hard-coated finish, combining low rotating weight with the strength required for pinion gear use.

The gear is precision machined on a dedicated gear machine, with carefully formed teeth for accurate engagement and true running. This supports smooth, vibration-free operation when used in a suitable 48-pitch drivetrain. The internal thread is finely formed to aid installation, while the tooth count is etched into the pinion for quick identification during setup and maintenance.

Each Hudy pinion is manually inspected and individually run-in. Its ultra-light construction makes it suitable where rotating mass is a consideration, while the hard-coated aluminium construction provides the stated balance of weight and strength. The 25T marking identifies the tooth count, and the 48 designation identifies the pitch.
