GPM MG223T/0.5M 40Cr Steel Motor Gear 23T Pinion for RC Motors  [MG223T/0.5M]

Product overview

This GPM MG223T/0.5M motor gear is an RC-scale pinion designed for small electric motors that match the listed dimensions. The gear has 23 teeth with a module of 0.5mm and a motor tooth diameter of 2.2mm, and uses a round-shaped motor hole secured by two 3x3 set screws. Material and finish focus on durability and consistent meshing under normal model use.

Installation notes: verify the motor shaft diameter and module match the 0.5mm specification before fitting, slide the gear onto the motor shaft so teeth mesh cleanly with the spur gear, then secure using the two 3x3 set screws. Check alignment and backlash at low throttle to confirm correct engagement before running at full power.

Tuning role: as a direct replacement pinion, this gear is intended to restore proper gear mesh and offer improved wear resistance compared with worn stock parts, helping maintain consistent transmission response in model setups. Always confirm gear parameters with your motor and spur gear to ensure compatibility.
