32T 0.8Mod Safe-D5 Pinion Gear (ARA311015)
32T 0.8Mod Safe-D5 Pinion Gear (ARA311015)
Designed for RC car powertrains, this rugged steel pinion gear features 32 teeth and a 0.8 modulus with a Safe-D profile, engineered to reliably transfer motor torque to the drivetrain in demanding conditions.
Fits a 5 mm motor shaft and is designed with a threaded set screw hole; it ships with a 4 mm M4 set screw and a 3.2 mm E-clip to keep the pinion secured on the shaft. The gear's wide tooth profile promotes smooth engagement with the spur gear, and the D-shaped bore aligns with the shaft to maintain engagement even if the set screw backs out.
