MG219T/0.5M 19T Motor Pinion 0.5mm Module 40Cr Steel for RC Motors by GPM  [MG219T/0.5M]

Motor Pinion Technical Overview

The MG219T/0.5M pinion features a 19-tooth design at a 0.5mm module, intended to mesh with spurs and motors sized for a 2.2mm motor tooth diameter. It is made of 40Cr steel with a surface hardening process to reduce wear and extend service intervals.

Fitment specifics include a round bore compatible with standard 2.2mm motor tooth diameter interfaces and dual 3x3 set screws for retention. Before installation, check the spur gear module and tooth count to ensure proper engagement and prevent accelerated gear wear.

Fitting advice: position the pinion flush to the shaft shoulder when applicable, tighten the 3x3 set screws in stages and alternate between them to maintain alignment, and confirm mesh by testing under normal load conditions. Note that altering pinion size or mesh settings will change acceleration and top speed, so log changes for tuning control.
