Maximum is different depending on gear ratio **Q: What is the backlash specification on this unit?** A: Have used 5 of these. Can not detect any backlash. Gearboxes are very well made and different motor mountings are available. We use these on CNC drives with100 or so cycles daily and have not had any problems. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great! Heavy Duty and affordable for what it is. *by on Reviewed in the United States 1 December 2025* This unit is super solid and is a great price for what you get. Gearbox comes fully lubricated and is factory sealed. so don't expect to open it easily (not that you'd need to). It's full of oil and you'd need to remove the rubber gasket without damaging it somehow.The biggest issue I had was finding the appropriate hardware for driving the input side of the gearbox. The main input has an odd inner diameter of 11mm (7/16") with a 4mm wide key and I underestimated how hard it would be to find appropriate components to drive this with a larger shaft. With that said, the manufacturer included coupler that adapts this down to an 8mm d-shaft and that fits standard sized servos traditionally used for this. ### ⭐⭐⭐⭐ Check the dimensions! *by on Reviewed in the United States 11 June 2024* Solidly built, smooth movement with no backlash, but I had to return two of them because the mounting holes for the NEMA 23 motor were on 49 mm centers, not the expected 47 mm (see the photo for the difference) ### ⭐⭐⭐⭐⭐ Good quality low price. *by on Reviewed in the United States 24 April 2025* This was a good quality gearbox and the price was very good. Being used in a prototype to determine life. ## Frequently Bought Together - CNCTOPBAOS NMRV030 Worm Gear Reducer Speed Ratio 10:1 Aluminum Alloy Square RV30 NMRV30 Worm Gearbox Speed Reducer for Nema23 Stepper Motor 11mm Input and 14mm Output Shaft - 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 - Shaft Sleeve 1/4Inch(6.35mm) Shaft Motor to 11mm Bore Adapter for RV030 Worm Gear Speed Reduce --- ## 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/542135168-cnctopbaos-nmrv030-worm-gear-reducer-speed-ratio-10-1-rv30](https://www.desertcart.tn/products/542135168-cnctopbaos-nmrv030-worm-gear-reducer-speed-ratio-10-1-rv30) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-09*
