This MG214T/0.5M motor pinion is an RC-scale gear made for motors that match the specified tooth profile. Constructed from 40Cr steel, it offers a hardened metal option where a compact 14T pinion is required. The pinion uses a 0.5mm module and a motor tooth diameter of 2.2mm with a round motor bore to suit common motor shafts.
Design notes: the pinion has 14 teeth (14T), a 0.5mm module, and a round central hole. It secures to the motor shaft using two 3x3 set screws placed opposite each other for balanced clamping. Verify your motor shaft and gear mesh dimensions before purchasing to ensure compatibility.
Installation and tuning guidance: when fitting this pinion, set mesh carefully so teeth engage cleanly with the spur gear and tighten the set screws evenly to reduce the chance of slippage. Treat the pinion as a direct replacement for motors that accept a 0.5mm module and 2.2mm motor tooth diameter, and adjust gearing gradually to preserve drivetrain reliability.
