It's not aerospace grade $500 set but it's fine for what it is. The screw rod is SUPER HARD and I would try to design my project around the available sizes and avoid cutting it. Well packaged and ball screw rod and ball screw is double packed within a cardboard tube inside a cardboard box. The bearing blocks, aluminum mount and screws are well packed too. ## Frequently Bought Together - 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) - ANWOK 2Pcs Linear Guide Rail HGR20-800mm with 4Pcs HGH20CA Square Type Carriage Bearing Block Linear Rail Set Slide Guide Rod Overall Length 31.5 inch(800mm) for DIY CNC Routers Lathes Mills - ANWOK Ball Screw RM/SFU1605-600mm 16mm with Metal Deflector Ball Screw Nut Housing Bracket and End Supports Bearing BK/BF10 for CNC Project DIY, 92337D14T5W917AB11RJLVU --- ## 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.sn/products/89760392-250mm-ball-screw-sfu1605-250mm-ballscrew-rm1605-250mm-with-ballnut](https://www.desertcart.sn/products/89760392-250mm-ball-screw-sfu1605-250mm-ballscrew-rm1605-250mm-with-ballnut) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-15*
