Motor Gear 22T 48 Pitch Module 0.5mm MG522T/0.5M (5mm) by GPM  [MG522T/0.5M]

Product snapshot for gearing and tuning

The MG522T/0.5M pinion is a 22-tooth, 48-pitch component manufactured from 45 steel with a 0.5mm module and a 5mm motor tooth diameter. It is intended for hobby electric models that require a 48-pitch pinion mating to a corresponding spur and a 5mm shaft interface.

As the initial gearing element, this pinion affects acceleration and top speed depending on tooth count. A 22T pinion leans toward quicker initial acceleration compared with larger pinions. The 45 steel composition balances hardness and toughness for hobby-level durability under repeated engagement.

Fitment tips—confirm the pinion’s 48-pitch and 0.5mm module match your spur, ensure the 5mm shaft seats correctly, and secure with the recommended fastening approach. Set mesh carefully and re-check after a short run-in to allow parts to settle. Apply minimal gear-friendly lubricant if aiming to reduce noise.

Compatibility notes—match numeric gear characteristics rather than chassis labels when checking fit. Use the pinion as a tuning element to refine drivetrain ratios for specific performance goals.
