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

48-pitch motor pinion overview

This MG526T/0.5M motor pinion is an RC-scale 26-tooth component machined from 45 steel, specified for 48 pitch and a module of 0.5mm. The motor tooth diameter is 5mm, matching many small electric motor shafts used in on-road and off-road hobby cars.

In practice this pinion is used to alter final drive ratio or to replace a worn pinion without changing the motor. Because it is 48 pitch with module 0.5mm, it meshes with spur gears cut to the same standards; confirm both pitch and module before swapping parts.

Installation tips: maintain correct axial alignment and set mesh for minimal backlash while avoiding excess preload on bearings. Verify that your grub screw or other retention method suits a 5mm motor tooth diameter and tighten to the motor mount hardware torque recommended by the motor maker.

Tuning note: fitting this 26T pinion raises theoretical top speed compared with smaller pinions while reducing low-end acceleration. Make incremental changes and test to find the best balance for track conditions and your battery/motor combination.
