0.5M 22T 40Cr Motor Pinion MG322T/0.5M (3.175mm Tooth Diameter) by GPM  [MG322T/0.5M]

Fortified 40Cr 22-tooth motor pinion

This 22T motor gear is intended for RC motor applications and is identified by its main measures: 22 teeth, 0.5mm module, and a motor tooth diameter of 3.175mm. The component is formed from 40Cr steel with a hardened black finish to deliver better wear resistance than non-hardened versions.

Design notes: the pinion has a round centre bore sized to suit motors with the specified tooth diameter and is clamped to the motor pinion shaft using two 3x3 set screws, providing a secure mechanical connection. These details support stable gear mesh under typical operating loads.

Selection guidance: ensure your motor uses a 0.5mm module and a 3.175mm motor tooth diameter before ordering. During installation, check engagement with the spur gear and apply suitable thread locking to the set screws when needed.

Maintenance and tuning: switching to a hardened 40Cr steel pinion is a standard upgrade for builds requiring improved longevity in the drivetrain; use this part where the dimensions are a match.
