It came in quick and packaged nicely. No issues with it. ### ⭐⭐⭐⭐⭐ Perfect groove size for 4.7mm brake line *by I***B on February 9, 2023* 7 of these are being used in a 4.7mm brake line tubing straightening jig. The tubing material is copper-nickel, so the steel outer bearing groove has no difficulty at all straightening it out. They work great, even though the mounting hole is only 4mm, but I'm using M4 10.9 allen head screws, so 7 of them working together is strong enough. ## Frequently Bought Together - Atoplee 10pcs U Groove Sealed Guide Pulley Miniature Bearing, (ID) 4mm x (OD) 13mm x (Thickness) 7mm Bearing Steel Pulley Wheels Set - uxcell 683ZZ Ball Bearing 3mm x 7mm x 3mm Double Shielded Deep Groove Bearings, Carbon Steel 20pcs - Fdit 20pcs V623ZZ V Groove Ball Carbon Steel Bearing Pulley for Rail Track Linear Motion System 3x12x4mm --- ## 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.vu/products/181539042-atoplee-10pcs-u-groove-sealed-guide-pulley-miniature-bearing-id](https://www.desertcart.vu/products/181539042-atoplee-10pcs-u-groove-sealed-guide-pulley-miniature-bearing-id) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-05*
