The GPM MTG4820T is a hard steel motor gear with a 48 pitch tooth form and 20 teeth, intended for reliable mesh under extended service. The component features a 3.175mm bore and a 0.5mm tooth spacing, making it compatible with common motor shaft diameters and standard pinion interfaces. For best results, check backlash and alignment during installation and ensure secure fastening on the motor shaft to avoid slippage under torque.
