Motor pinion overview

This RC-scale motor gear is a direct replacement pinion designed for motors that match a 0.5mm module and a motor tooth diameter of 3.175mm. The gear has 19 teeth (19T) and a round motor bore secured by two 3x3 set screws, providing a simple swap for compatible setups.

Constructed in 40Cr steel with hardened black treatment, the gear is engineered for improved wear resistance and consistent meshing under typical RC drivetrain loads. Use this part when you need a like-for-like replacement or when fine-tuning gear engagement for your model.

Before purchasing, confirm your motor's pinion parameters—module 0.5 and 3.175mm tooth diameter—to ensure fitment, and verify the shaft and bore alignment for secure fastening with the two 3x3 set screws.

Will this pinion fit my motor?

It fits motors that use a 0.5mm module and a 3.175mm motor tooth diameter, so check those dimensions on your motor before ordering.

How is the pinion secured to the motor?

The round motor bore is held in place with two set screws sized 3x3, which clamp the pinion to the motor shaft when tightened evenly.

What are the material and durability characteristics?

The gear is made from 40Cr steel with a hardened black treatment to improve wear resistance and maintain stable transmission in RC drivetrains.
