33T Mod1 Safe-D5 Pinion Gear (ARA311128)

This 33-tooth Mod1 Safe-D5 pinion gear is a tough steel component designed for RC models, converting motor rotation into drive with sturdy, long-lasting performance. It features a D-shaped hole that matches the motor shaft profile to help prevent drive loss if the set screw backs out and is sized for 5mm motor shafts for broad compatibility.

Included with the gear are an M4 x 4mm set screw and a 3.2mm E-clip to secure the pinion on the shaft. The gear offers a precision wide tooth profile for smooth engagement and a threaded set-screw hole for secure mounting, making it a reliable choice for demanding RC use.
