Hudy Aluminium Ultra-Light Pinion Gear 12T / 48 DY294012

The Hudy Aluminium Ultra-Light Pinion Gear - Hard Coated - 12T / 48 (DY294012) is an aluminium pinion gear for radio-controlled model drivetrains. This 12-tooth, 48-pitch gear is made from 7075 T6 aluminium and has a specially hard-coated surface. Its ultra-light construction is extensively machined to reduce rotating weight while retaining the strength required by the gear. The hard coating supports the stated durability of the gear during use, while the 12T / 48 specification identifies its tooth count and pitch for drivetrain gearing selection. The aluminium construction keeps the gear light, and its machined form is intended to limit rotating mass. The 7075 T6 aluminium specification and hard-coated finish define the gear's material and surface treatment.
