There was a slight curve to both rails (I did not take a picture), the curve didn't bother me for my purposes because I knew they would lay flat enough once I put some weight on them. I had to cut about 6" off each one (they were toolong) and they were extremely tough to cut, it dulled my horizontal bandsaw blade so I had to switch to a metal cutting chop saw with an abrasive wheel, which still took a while. I used these linear rails as drawer slides for a truck bed drawer I built. The slider has been in my truck for about 8 months, so far so good. The truck was driven on the beach a few times after install, and the rails and bearings stood up to the sand and all the bouncing through the rutted sand. I love the convenience of a sliding drawer whenever I go shopping for groceries too, I don't have to climb up into my truck to get bags that slide towards the cab. I have included pictures of the build, you can see the linear rails in the first picture, and the finished product in the last 2 photos. I have a couple modifications I want to make, such as adding tie down points to the box and a removeable divider to keep things closer to the tailgate when I am not using the full drawer.

These are perfectly machined and not made with flimsy, substandard materials. You just don't see this type of quality much anymore. They easily handled the load that I used them for (but rated much higher) - with very smooth gliding action. I can't say enough about the quality of these pieces - and at an affordable price! Would highly recommend these rails for most any application where quality is critical. ## Frequently Bought Together - GUWANJI 2Pcs SBR20-800mm Linear Slide Guide Rail with 4Pcs SBR20UU Bearing Block, Linear Sliding Guideway Length 31.5 inch(800mm) for Fully suppoeted Shaft Rod - 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 - 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 --- ## 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/352428913-2pcs-sbr20-400mm-15-7-inch-linear-fully-supported-rail](https://www.desertcart.co.th/products/352428913-2pcs-sbr20-400mm-15-7-inch-linear-fully-supported-rail) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-06*
