In my case, I'm converting a manual lathe to CNC, so this unit simplified the mounting of the motor driven end.Recommended ### ⭐⭐⭐⭐ Easy way to mount stepper motor and align with lead screw *by D***K on January 22, 2025* This is a great way to mount the stepper motors - makes the 'build your own' CNC much easier. Makes aligning the motor with the lead screw a no-brainer. Downside: expensive - cost more than the stepper motor. I first purchased a steel mount then discovered the same thing in aluminum which was much lighter which I liked. ### ⭐⭐⭐⭐ Awesome product but needs some adjustment parts *by K***S on October 13, 2024* This is an awesome adapter but the coupler to ball screw needs to be longer (40mm) and it’s made to go on the very end of table so if you mount it further up on the table then you need a wood shim to make it level. I would still buy this again. ## Frequently Bought Together - Coavoo Motor Mounting Bracket and BK12 Bearing End Support Block for Nema 23 Stepper Motor and Ball Screw 16mm Ballscrew SFU1604 SFU1605 SFU1610 as CNC Kit Parts - GUWANJI 700mm Ball Screw SFU1605 700mm Ballscrew RM1605 700mm with a Ballnut + 1 Set BK12 and BF12 Support, and Coupler for CNC Machine(Diameter 16mm, 5mm Pitch) - Zeberoxyz 2PCS 10mm to 10mm Aluminium Plum Flexible Shaft Coupling Diameter25mm Length30mm 10x10mm Motor Connector Flexible Coupler for 3D Printer CNC Machine and Servo Stepped Motor（10x10mm） --- ## 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.co.th/products/525862732-motor-mounting-bracket-and-bk12-bearing-end-support-block-nema](https://www.desertcart.co.th/products/525862732-motor-mounting-bracket-and-bk12-bearing-end-support-block-nema) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-26*
