MG220T/0.5M 20T Motor Pinion Summary

The MG220T/0.5M is a 20-tooth motor pinion supplied as a replacement or spare for motors matching its tooth profile and shaft dimensions. Essential measurements provided include 20T, module 0.5mm, and motor tooth diameter 2.2mm. The bore is round and the part is retained with two 3x3 set screws.

Manufactured from 40Cr steel with a darkened finish, the pinion reduces initial surface glare and supports baseline wear resistance versus untreated materials. This material selection aims to keep tooth geometry stable under typical hobby loads and to ensure consistent engagement with compatible spur gears.

Always verify the pinion module and motor tooth diameter against your motor and spur prior to purchase. Proper mesh and shaft seating are vital: slide the pinion onto the shaft, set correct backlash with the spur, then tighten the two set screws evenly to avoid shifting. Use only with motors that match the listed specifications.
