GPM Racing 40CR Steel Motor Gear 22T (Module:0.5mm,motor Tooth Diameter:3.175mm) (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.

How do I confirm the pinion will fit my motor?

Use calipers to measure the motor pinion tooth diameter and confirm a module of 0.5mm; only order if both values match the specifications listed.

What method secures the pinion to the shaft?

The pinion is secured by two 3x3 set screws that press against the shaft; tighten evenly and consider thread locking for high-vibration applications.

Why choose 40Cr material for a pinion?

40Cr steel with a hardened finish provides enhanced wear resistance, helping the pinion maintain tooth profile and service life under regular RC use. Write Product Review Please sign in your account before you can write any review. Sign In Close
