Perfectly matched with Nema23 stepper motors for general automation lines, conveyor systems, feeding devices, rotary tables and DIY mechanical projects - Standardized Mounting & Shaft Specifications: Features a 60mm x 60mm (2.36 inch x 2.36 inch) standard Nema23 flange with 47mm x 47mm (1.85 inch x 1.85 inch) motor mounting hole spacing, matched with an 11 mm (0.43 inch) input bore diameter and 14 mm (0.55 inch) output shaft diameter, ensuring seamless installation and full compatibility with most mainstream Nema23 stepper motors/servo motors on the market - High-Strength Aluminum Alloy Enclosure: Made of die-cast aluminum alloy housing, delivers excellent thermal dissipation performance, high rigidity and corrosion resistance; compact structure adapts to limited installation space while effectively extending the service life of the gearbox - Smooth Transmission & Standard Worm Gear Tolerance:​ Adopts high-quality worm gear and bearing structure for stable transmission and low operating noise. As with all standard worm gearboxes, this unit has some normal gear lash/backlash inherent to the worm drive design — acceptable for general load driving and speed control. It is not intended for precision machining or high-accuracy positioning that require extremely tight reverse clearance - Wide Compatibility with Important Selection Notes:​ Adapts to most general automation scenarios, including CNC router auxiliary axes, small engraving machines, 3D printers, DIY robotic arms, automatic feeding devices and student projects. Pre-lubricated and debugged before leaving the factory, ready to use without additional maintenance. Please note:​ This gearbox is reversible/non-self-locking — the output shaft can turn the input shaft under back-drive loads ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09HGY6FSJ | | Best Sellers Rank | #78,719 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #29 in Gearboxes, Gearheads & Speed Reducers | | Brand Name | CNCTOPBAOS | | Customer Reviews | 3.8 3.8 out of 5 stars (4) | | Included Components | Worm Gear Reducer | | Item Highlight | Speed Ratio 20:1 Worm Drive, 60mm Flange, 11mm Input Shaft, 14mm Output Shaft, RV30 NMRV30 Square Worm Gearbox Speed Reducer | | Manufacturer | CNCTOPBAOS | | Material Type | Aluminium | | Model Number | 3 | | Number of Items | 1 | | Part Number | 3 | ## Product Details - **Brand:** CNCTOPBAOS - **Manufacturer:** CNCTOPBAOS - **Material:** Aluminium - **Number of Items:** 1 ## Images ![CNCTOPBAOS NMRV030 Worm Gear Reducer Gearbox 20:1 for Nema23 Stepper Motor - Image 1](https://m.media-amazon.com/images/I/41bhc5P3MpL.jpg) ![CNCTOPBAOS NMRV030 Worm Gear Reducer Gearbox 20:1 for Nema23 Stepper Motor - Image 2](https://m.media-amazon.com/images/I/51ANWME9RHL.jpg) ![CNCTOPBAOS NMRV030 Worm Gear Reducer Gearbox 20:1 for Nema23 Stepper Motor - Image 3](https://m.media-amazon.com/images/I/51JKxVcRayL.jpg) ![CNCTOPBAOS NMRV030 Worm Gear Reducer Gearbox 20:1 for Nema23 Stepper Motor - Image 4](https://m.media-amazon.com/images/I/41sIzW3bowL.jpg) ![CNCTOPBAOS NMRV030 Worm Gear Reducer Gearbox 20:1 for Nema23 Stepper Motor - Image 5](https://m.media-amazon.com/images/I/41+4zV+5siL.jpg) ## Available Options This product comes in different **Style** options. ## Frequently Bought Together - CNCTOPBAOS NMRV30 Worm Gearbox Speed Reducer NMRV030 Worm Gear Reducer Speed Ratio 20:1 RV30 Square Type for Nema23 Stepper Motor Output Hole 14mm Shaft NMRV-030 - CNCTOPBAOS Output Double Shaft Diameter 14mm 0.55" Dual Output Shaft Length 130mm Fit for Worm Reducer Gearbox NMRV030 RV030 Nema23 Stepper Motor with Gaskets S Ring Corner pin - CNCTOPBAOS 8mm to 11mm Stepper Motor Shaft Sleeve 8x11mm Bore Adapter Turbine Reducer Shaft Sleeve for RV030 Worm Gear Speed Reduce RV30 NMRV030 Gearbox 0.31inch --- ## 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.tn/products/483173891-cnctopbaos-nmrv030-worm-gear-reducer-gearbox-20-1-for-nema23](https://www.desertcart.tn/products/483173891-cnctopbaos-nmrv030-worm-gear-reducer-gearbox-20-1-for-nema23) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-24*
