GPM MG215T/0.5M 40Cr Steel Motor Pinion Gear 15T (module 0.5mm, 2.2mm bore)  [MG215T/0.5M]

Motor pinion gear, 15T

This GPM MG215T/0.5M pinion is an RC-scale motor gear designed for small electric motors that share the same module and bore dimensions. The gear has 15 teeth at 0.5mm module and a 2.2mm motor tooth diameter, with a round motor gear hole built to accept standard motor shafts of the stated size.

Manufactured from 40Cr steel, the part is heat-treated for improved wear resistance compared with untreated stock gears. The gear secures to the motor shaft using two set screws sized 3x3, providing a simple mechanical clamp for reliable seating when properly torqued.

Practical notes for fit and use:

• Check your motor’s module (0.5mm) and motor bore (2.2mm) before ordering to confirm compatibility.
• Ensure the motor shaft is clean and free of burrs before fitting, and tighten both 3x3 set screws evenly to avoid misalignment.
• Use this pinion as a direct replacement where the 15T, 0.5mm module and 2.2mm bore match the existing drivetrain, it is intended for RC model transmissions only.
