I used these for a router sled. There were two drawbacks. The first was hunting for the correct screw size of the holes on the mounting blocks. (Metric6 by the way) The second if a little bit of flex in the rails. For a full size router I may have to go back and add some steel underneath the rails so they don't sag. ## Frequently Bought Together - CNCMANS SBR20-1200mm Linear Rail Linear Rails and Bearings Kit 2Pcs SBR20 1200mm Long Fully Supported Shaft Guide with 4Pcs SBR20UU Linear Bearing Slide Block Linear Guide for CNC Equipments - VEVOR Linear Rail Slide SFC20-1000mm 2 PCS 39.4 in/1000mm SFC20 Guide Rails 4 PCS SC20 Slide Blocks 4 PCS Rail Supports Linear Rails and Bearings Kit for Automated Machines CNC DIY Project - Shaft Collar for SBR20 Linear Rail Stop, 20mm Bore 40mm OD 12mm Thickness Aluminum Alloy Anodized Clamp-On with M5 Set Screw, Locking Collars for CNC and Linear Motion Systems --- ## 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.ma/products/500819324-sbr20-1200mm-linear-rail-linear-rails-and-bearings-kit-2pcs](https://www.desertcart.ma/products/500819324-sbr20-1200mm-linear-rail-linear-rails-and-bearings-kit-2pcs) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-10-23*
