Whether for professional workshops or DIY projects, this linear guide rail set meets diverse precision motion requirements ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0FFMQG4NS | | Best Sellers Rank | #49,748 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #45 in Linear Motion Guides | | Date First Available | June 26, 2025 | | Item Weight | 5.15 pounds | | Manufacturer | iMetrx | | Package Dimensions | 9.17 x 4.69 x 2.01 inches | ## Images ![HGR20 Linear Guide Rail Kit - 2 Pcs 500mm Rails + 4 Pcs HGH20CA Bearing Blocks High Precision, Anti-Rust for 3D Printers, CNC Routers, Lathes & DIY Automated Machines - Image 1](https://m.media-amazon.com/images/I/61yiLHOczxL.jpg) ## Available Options This product comes in different **Size, Number Of Items** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice and Heavy for CNC Machine *by E***H on October 26, 2025* Ordered a set of these for a shop CNC upgrade. Am pleasantly surprised with the rail uniformity and size. The bearing blocks are nothing special, but they are generic and can be replaced easily if needed. Will be purchasing another rail set for upgrading the y-axis. ### ⭐⭐⭐⭐⭐ #1 *by J***N on October 25, 2025* Good ### ⭐⭐⭐⭐⭐ Nice set of HGH20 blocks for the price *by P***N on September 2, 2025* This seems to be a good, solid assembly for a low price. I have not had the chance to install them yet but after cleaning and relubricating the blocks they operate smoothly by hand on the HGR rails. Ball oilers and plastic displacement slides are included so mounting on the guide rail is simple. These should have the size and rigidity needed for use in rebuilding my current round linear guide rails on a small CNC router, and hopefully they can improve the precision and reduce the deflection that is present. This particular kit seems to be rather impractical since the rails are 200 mm in length and 2 blocks are provided for each rail. Since the blocks are about 75 mm long, the effective maximum travel length is about 120 mm with just one block. Two blocks per rail makes little sense for short rails like this since it is unnecessary, and with ball oilers installed there would be essentially no travel distance left. However, I plan to purchase longer rails for my system. I am sure these are a long way from Hiwin equipment, but so is the price. I can’t know for sure until they are installed but these seem to be reasonably well made and I think they should work fine. If not I will edit this review later, but for now they seem to be pretty good. --- ## 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.tn/products/806699564-hgr20-linear-guide-rail-kit-2-pcs-500mm-rails-4](https://www.desertcart.tn/products/806699564-hgr20-linear-guide-rail-kit-2-pcs-500mm-rails-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-23*
