Perfect sizing and worked perfectly to align my vise. ### ⭐⭐⭐⭐⭐ Very smooth. *by B***G on November 15, 2023* I used these with 3/4” steel rods to add sliding extension support to miter saw station. Extension slides effortlessly, even under load. ### ⭐⭐⭐ The bearings are not very smooth... *by K***Y on July 2, 2021* The price was good, but the bearings are not very smooth. Even on a highly polished, stainless steel rod, you can definitely vibration caused as the individual bearings roll through their respective tracks. Luckily, my use-case only relies on these bearings for initial setup and adjustment. When the automation is running, the bearings won't be moving, so these work well-enough for this type of implementation. --- ## 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.gr/products/105380478-uxcell-lmk20uu-square-flange-linear-ball-bearings-20mm-bore-dia](https://www.desertcart.gr/products/105380478-uxcell-lmk20uu-square-flange-linear-ball-bearings-20mm-bore-dia) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-11*
