This Nema 17 stepper motor delivers a holding torque of 0.52Nm(73.64oz.in) and features our high-precision MG series gearbox with a 50:1 gear ratio. Unlike the EG series' steel gears, the MG series utilizes durable powder metallurgy gears, offering an optimal balance of precision and cost-effectiveness for your applications.
The integrated shaft coupling design allows for easy motor or gearbox replacement, providing flexibility for your projects.
