Compact Motor Pinion Details

This 40Cr steel motor gear (22T) is an RC-scale pinion made for small electric motors that use a module 0.5mm gear mesh. The hardened black surface treatment raises surface hardness and boosts wear resistance under normal model power loads, while the circular motor hole is sized for a 2.2mm motor tooth diameter.

Installation notes: the gear is secured to the motor shaft with two set screws sized 3x3, and the round bore accepts motors matching the specified shaft and tooth diameter. For reliable engagement check the module 0.5mm pairing with your spur gear and confirm the 22T tooth count fits your gearbox geometry before fitting.

Tuning role: fit this pinion when you want a durable, compact gear to alter final drive ratios in electric RC models; changing pinions that share the same module and motor tooth diameter lets you tune acceleration versus top speed without replacing the motor or spur gear.

Which motor shafts will accept this pinion?

This pinion fits motors whose shaft and pinion interface match a 2.2mm motor tooth diameter and that accept module 0.5mm pinions. Always verify shaft diameter and set-screw clearance before mounting.

Any tips for securing the gear evenly?

Slide the gear to the desired position, then tighten the two 3x3 set screws alternately and incrementally to avoid shaft damage and to maintain correct backlash.

How should I check the gear during maintenance?

Regularly inspect tooth faces for pitting or burrs, clear any debris from the mesh, and re-check set-screw tightness after the first runs to ensure reliable operation.
