Reel works better than when new, bearings are smooth and a perfect fit replacement. ### ⭐⭐⭐⭐⭐ A good set of bearings *by on Reviewed in the United States 17 May 2025* These work great and are a good quality. Please ensure the measurements before ordering. ### ⭐⭐⭐⭐⭐ Perfect fit for my Daiwa fishing reels *by on Reviewed in the United States 22 January 2024* These are a perfect fit for the bearings used in Daiwa reels. Since they were so cheap, I bought just to try, and now I have 9 spares for the next time it fails. They fit perfectly and are smooth turning, just like what came with the reel. I fish a lot and go through bearings about every 2 years. --- ## 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.us/products/468147337-uxcell-mr84-2rs-deep-groove-ball-bearings-4mm-inner-dia](https://www.desertcart.us/products/468147337-uxcell-mr84-2rs-deep-groove-ball-bearings-4mm-inner-dia) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-18*
