MG322T/0.5M 22T 40Cr Hardened Motor Gear (0.5mm Module, 3.175mm) by GPM  [MG322T/0.5M]

Hardened 22T motor pinion summary

This 22-tooth motor gear is intended for RC motor installations and is characterised by 22T, module 0.5mm, and motor tooth diameter 3.175mm. The part is produced from 40Cr steel with a hardened black surface finish to improve wear resistance compared with non-hardened gears.

Design features: the pinion incorporates a round centre hole sized for motors that match the specified tooth diameter and is clamped to the motor shaft with two 3x3 set screws, forming a dependable mechanical connection. These features support consistent gear mesh and reduce slippage under normal operating loads.

Fitment notes: verify that your motor pinion uses module 0.5mm and a 3.175mm tooth diameter before ordering. When fitting, check mesh against the spur gear and apply appropriate thread locking to the set screws if required for your build.

Upgrade use: swapping to a hardened 40Cr steel pinion is a typical upgrade to enhance durability in drivetrains subject to wear; it will function as a direct replacement where dimensions match.
