I think they may be the same ones that were used originally. They are quiet and effective. At a dollar per bearing they are pricey but you can probably find these elsewhere at bulk prices. Thanks to the seller for making the dimensions so confusing. 1/4"x 1/2" x 3/16" is indeed the correct measurement. They are NOT 1/4mmx1/2mmx3/16mm. ## Frequently Bought Together - R188 Open Deep Groove Ball Bearing, 1/4"mmx1/2"mmx3/16"mm Fidget Spinner Bearing with Nylon Caged (10 PCS) - 300 Pack Small Magnet, 4x2mm Refrigerator Magnets Rare Earth Magnets Neodymium Magnet for Crafts, Whiteboard, Kitchen Cabinet - 240 Pack Small Magnets,5x2mm Refrigerator Magnets Rare Earth Magnet Neodymium Magnet for Crafts, Whiteboard, Kitchen Cabinet --- ## 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/356797952-r188-open-deep-groove-ball-bearing-1-4-mmx1-2](https://www.desertcart.gr/products/356797952-r188-open-deep-groove-ball-bearing-1-4-mmx1-2) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-27*
