45 Steel 26T Motor Pinion MG526T/0.5M (48 Pitch, 0.5mm) by GPM  [MG526T/0.5M]

Motor pinion for 48 pitch systems

This MG526T/0.5M motor pinion is a 26-tooth component made from 45 steel, sized for 48 pitch and module 0.5mm. The 5mm motor tooth diameter is compatible with many compact hobby electric motors used in a variety of RC vehicles.

It is commonly used to change final drive ratio or to replace a worn pinion without swapping the motor. Ensure both pitch and module match the mating spur gear before fitting to avoid inconsistent meshing.

Fitment tips: check axial alignment, set a small amount of backlash to avoid binding, and confirm the retention method on your motor fits a 5mm tooth diameter. Tighten fastenings to the recommended torque values for your motor mount hardware.

Tuning effect: using this 26T pinion increases theoretical top speed versus smaller pinions while reducing initial acceleration. Make adjustments in small steps and validate performance with test runs to find the optimal gearing for your setup.
