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 | B09HGH4S3F | | Best Sellers Rank | #82,622 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #4 in Gearboxes, Gearheads & Speed Reducers | | Brand Name | CNCTOPBAOS | | Customer Reviews | 3.9 3.9 out of 5 stars (10) | | Included Components | Worm Gear Reducer | | Item Highlight | Speed Ratio 10:1 Worm Drive, 60mm Flange, 11mm Input Shaft, 14mm Output Shaft, RV30 NMRV30 Square Worm Gearbox Speed Reducer | | Manufacturer | CNCTOPBAOS | | Material Type | Aluminum | | Model | 1 | | Number of Items | 1 | | Part Number | 1 | | Shaft Diameter | 14 millimeters | ## Product Details - **Brand:** CNCTOPBAOS - **Manufacturer:** CNCTOPBAOS - **Material:** Aluminum - **Number of Items:** 1 - **Shaft Diameter:** 14 millimeters ## Images ![CNCTOPBAOS NMRV030 Worm Gear Reducer Gearbox 10:1 for Nema23 Stepper Motor - Image 1](https://m.media-amazon.com/images/I/71-OGBbyNmL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Whats max power from the motor this gearbox can hold?** A: The chart with specifications provides the power recommendations.
