23T 0.5mm Module Motor Gear

This MG323T/0.5M motor gear is an RC replacement pinion sized for motors that meet the listed dimensions. The component uses a 0.5mm module, 23 teeth and a motor tooth diameter of 3.175mm, and the hardened black finish helps reduce surface wear compared with untreated parts.

Fitment and function: the gear has a round motor bore sized for the specified motor tooth diameter and fastens to the motor shaft with two 3x3 set screws. Always confirm module, tooth count and shaft interface before purchase to ensure correct mechanical compatibility.

Tuning role: suitable for drivetrain adjustments where small tooth count or material hardness changes influence gear engagement, wear rate and transmission smoothness. Use this part when precise module and shaft match is necessary for reliable meshing with the corresponding spur gear.

What motor shaft size does this pinion fit?

It is specified for a motor tooth diameter of 3.175mm; check that your motor matches this measurement.

How is the pinion attached to the motor shaft?

Can this gear be used across different motor models?

Use only with motors that match the indicated module, tooth count and 3.175mm tooth diameter; confirm compatibility prior to fitting. Write Product Review Please sign in your account before you can write any review. Sign In Close
