Overview of the 22T Pinion

The 40Cr steel motor gear (22T) is an RC pinion specified for small electric motors that operate with a module 0.5mm gear mesh. Its hardened black surface treatment increases surface hardness and improves resistance to wear under normal model power conditions, and the circular motor hole is sized for a 2.2mm motor tooth diameter.

Installation notes: attach the gear to the motor shaft using the two 3x3 set screws, ensuring the shaft and tooth diameter match the round bore. Verify the module 0.5mm engagement with your spur gear and confirm that the 22T tooth count fits your gearbox arrangement prior to final assembly.

Tuning role: this gear provides a compact, wear-resistant option for adjusting final drive ratios in electric RC models; swapping pinions with the same module and motor tooth diameter is an effective method to tune acceleration versus top speed without changing the motor or spur gear.

Is this pinion compatible with brushless motors?

Compatibility depends on the motor shaft and pinion interface, not the motor type. If the motor accepts a 2.2mm motor tooth diameter pinion and can be clamped with two 3x3 set screws, it can be fitted. Check shaft dimensions and clearance first.

Can changing to this 22T affect top speed?

Yes. Moving to a different tooth count alters the final drive ratio; a smaller pinion increases top speed but reduces acceleration, while a larger pinion does the opposite. Keep the module and motor tooth diameter consistent when swapping.

What routine checks should I perform after fitting?

After initial runs check set-screw tightness, inspect gear teeth for early wear or damage, and ensure the mesh remains free of grit or debris to maintain reliable operation.
