21T 0.8Mod Safe-D5 Pinion Gear (ARA311004)
This 21-tooth, 0.8-module Safe-D5 pinion gear is a rugged steel pinion designed for high‑performance RC drivetrains. It’s built to transfer power from a 5 mm motor shaft to the spur gear with smooth, reliable engagement in demanding conditions. The kit includes the pinion gear along with an M4 x 4 mm set screw and a 3.2 mm E-clip for secure shaft retention.
Durable steel construction and a precisely machined wide tooth profile promote quiet, steady operation. The D-shaped hole matches the motor shaft to help keep drive and braking secure even if the set screw backs out, and the threaded set-screw hole ensures a precise, repeatable fit. Suitable for 5 mm shafts, this pinion is ready for install with the included hardware.
