15T Steel Pinion Durability

The MG215T/0.5M 15T pinion is intended for small electric RC motors that use a 0.5mm module and 2.2mm bore. Its compact tooth profile is suitable for tight gearbox layouts.

Forged from 40Cr steel and heat-treated, this pinion offers improved wear resistance compared with untreated stock gears. Retention uses two 3x3 set screws which, when fitted correctly, provide a secure clamp to the motor shaft.

Notes on longevity:

Confirm the 0.5mm module and 2.2mm bore to ensure correct fitment.
Maintain a smooth shaft surface and tighten set screws evenly to avoid stress concentrations.
Replace the pinion if tooth wear or shaft damage becomes evident to protect the rest of the drivetrain.

How does heat treatment affect this pinion's lifespan?

Heat treatment increases hardness and wear resistance, which helps the gear resist pitting and deformation under normal RC loads.

Are the supplied set screws robust enough for repeated use?

The two 3x3 set screws are standard hardware; avoid excessive torque and inspect threads after multiple removals, replacing screws if threads show damage.

What signs indicate the pinion should be replaced?

Look for rounded or chipped teeth, uneven wear, or movement on the shaft. Replace the pinion to prevent further drivetrain damage.
