23T 0.8Mod Safe-D5 Pinion Gear (ARA311006)
A rugged 23-tooth, 0.8-module Safe-D pinion gear designed for RC car motors, delivering smooth power transfer to the spur gear for predictable speed and torque. The Safe-D bore is a D-shaped profile that mates with the motor shaft, helping keep the gear engaged even if the set screw loosens.
Constructed from tough steel for durability in demanding RC conditions, this pinion uses a precise wide tooth form for reliable meshing with the spur gear. It fits 5mm motor shafts and comes with an M4 x 4mm set screw and a 3.2mm E-clip to secure it in place, ensuring retention during operation.
