Technical pinion briefing

This 19-tooth motor pinion is intended as a direct swap for motors that require a 0.5mm module and 3.175mm tooth diameter. The pinion uses a round bore fastened by two 3x3 set screws for secure mounting.

Crafted in 40Cr steel with a hardened black surface, the pinion offers improved wear resistance and consistent meshing under standard RC drivetrain stresses. It is suitable for replacement or for adjusting gear ratios subtly.

Prior to purchase, double-check your motor's module and tooth diameter (0.5 and 3.175mm) and confirm shaft/bore alignment so the 3x3 set screws can hold the pinion firmly.

Can this pinion be used for ratio tuning?

Yes. Swapping to a different tooth count affects final drive ratio; this 19T pinion is suited for modest ratio changes when the module and diameter match your motor.

Is the hardened finish important?

The hardened black treatment increases surface durability and helps the pinion resist wear from repeated meshing, extending service life in many conditions.

Will the two 3x3 set screws prevent slipping?

When the bore is seated correctly and the set screws are tightened evenly, the dual 3x3 screws provide reliable clamping to reduce slippage on the motor shaft.
