Review: Working Well - Has worked well so far Review: Excellent torque from a small package. - I am using several of these to open/close doors in a display. The gear ratio is high enough to get good acceleration control and low enough that they can be back driven if someone moves a door manually. Original order of 12 was lost in shipping but quickly replaced. ## Features - High Torque Good Speed - 0.067 deg.

The gear ratio is high enough to get good acceleration control and low enough that they can be back driven if someone moves a door manually. Original order of 12 was lost in shipping but quickly replaced. ### ⭐⭐⭐⭐⭐ Quiet Strong Dependable. *by N***E on May 14, 2019* Used for a clay extruder. Very quiet and dependable. I just put it into service recently and this thing is strong enough to pull stumps! I was concerned with it having the nylon gears and they do offer a metal screw model for more $ but so far so good. It’s nice to know I have an option... ## Frequently Bought Together - STEPPERONLINE 27:1 Planetary Gearbox High Torque Nema 17 Stepper Motor 3D Printer DIY Camera - STEPPERONLINE NEMA 17 Stepper Motor (Economy Geared Stepper Motor) Alloy Steel Mounting Bracket ST-M1 - STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-Step Resolutions for Nema 17 and 23 Stepper Motor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/10243222-27-1-planetary-gearbox-high-torque-nema-17-stepper-motor](https://www.desertcart.vu/products/10243222-27-1-planetary-gearbox-high-torque-nema-17-stepper-motor) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-07*
