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 SBR16 1200mm Linear Rail Guide SBR16 Fully Supported Linear Slide Rail with 4Pcs Industry-Standard SBR16UU Slide Ball Bearing Block, DIY CNC Parts X Y Z Linear Actuator - (Pack of 4) Shaft Collar Set for Linear Rail SBR16, All in One Clamp-on Shaft Collar with M5 Set Screw, Bore 16mm, OD 35mm, Thickness 10mm - OrangeA Linear Rail 2PCS SBR16-2000mm, 2xLinear Guide Rails and 4X Square Type Carriage Bearing Blocks,CNC Rail Kit --- ## 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.jp/products/590927072-sbr20-1200mm-linear-rail-linear-rails-and-bearings-kit-2pcs](https://www.desertcart.jp/products/590927072-sbr20-1200mm-linear-rail-linear-rails-and-bearings-kit-2pcs) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-17*
