Pinion Gear Technical Snapshot

This RC pinion is produced from 45CR steel and intended as a direct swap for motors matching the given dimensions. It features 20 teeth (20T), a 48 pitch with module 0.5mm, and a rounded motor hole to suit motors with a 5mm motor tooth diameter.

Critical dimensions for setup: total thickness 10mm, tooth face thickness 5mm, and tooth face outer diameter 12mm. These figures help when setting proper mesh against the spur and confirming motor shaft and set screw positioning.

Fitting advice: ensure the rounded hole fully seats on the motor boss, fasten with the supplied 3x3 screw shaft, check axial placement for correct mesh engagement, and inspect mesh again after a brief run-in period. This component is for electric scale RC models only and not intended for real vehicles.

Packing includes

  • Motor Gear 20T - 1pcs
  • Screw Shaft 3x3 - 1pcs

Will this pinion seat on a 5mm motor boss reliably?

Yes, the rounded hole is sized for a 5mm motor tooth diameter; check for full contact on the boss and ensure the set screw tightens without slipping.

How durable is the 45CR material in sustained use?

45CR is commonly used for robust pinions and handles normal RC workloads well; under continuous heavy loads inspect for wear and adjust mesh as needed.

What measurement should I check first during installation?

Confirm the axial position so teeth meet mid-face and then verify overall thickness relative to your spur gear; hand-rotate the drive to ensure smooth engagement prior to running.
