Pinion Specification and Use

This 40Cr steel 22-tooth motor gear is an RC-scale pinion suited for small electric motors that require a module 0.5mm gear mesh. The hardened black finish enhances surface hardness and helps resist wear during normal model operation, while the round motor bore matches a 2.2mm motor tooth diameter.

Installation notes: the gear fixes to the motor shaft with two 3x3 set screws, and the round hole takes motors conforming to the stated shaft and tooth diameter. Before fitting, confirm the 0.5mm module mate with your spur gear and that the 22T count suits your gearbox layout.

Tuning role: use this compact, durable pinion when you need to tweak acceleration or top speed; exchanging pinions that share the same module and motor tooth diameter lets you adjust final drive without modifying motor or spur gear components.

Will this pinion fit my motor if I have a 2.2mm shaft?

Yes, provided the motor accepts a pinion with the specified 2.2mm motor tooth diameter and the shaft interface allows set-screw mounting. Measure the shaft and check clearance before installation.

How should backlash be set with this gear?

Set a small, even backlash by positioning the pinion relative to the spur while the drivetrain is static, then tighten the two 3x3 set screws alternately. Re-check mesh under slow rotation to verify engagement.

Is special care required for the black finish?

The hardened black treatment is durable, but you should still keep the gear clean and inspect for wear. Avoid aggressive cleaning chemicals and remove debris after runs to extend service life.
