| NEMA 17 Geared Stepper Motor TSL-42GP-42STH Series Datasheet
Please note that this gearbox is an economical planetary gearbox made of powder metallurgy materials. The backlash is 1–2° for 1-stage gearboxes, around 2° for 2-stage gearboxes, and 2–3° for 3-stage gearboxes. If you require lower backlash or superior gear materials (such as steel gears), please check our TSL-42PXG-42STH Series.
