The GPM MG323T/0.8M motor gear is CNC finished and hardened 40CR steel with a 23 tooth profile for 32 pitch gear trains. Its 0.8mm module and 3.175mm motor tooth diameter maintain correct mesh geometry across common hobby motors, delivering predictable wear characteristics under sustained torque. This component is intended as a direct replacement or upgrade where enhanced material strength and consistent tooth form extend service life in demanding running conditions.
