The double-sealed design keeps the lubricant inside and dirt out, which means the wheels spin smoothly and last longer — even with rough play. Made from tough chrome steel, these bearings feel sturdy and handle the stress of constant rolling and bumps without wearing out quickly. The size fits perfectly for my projects (8mm inner diameter, 12mm outer diameter), and the noise level is low, so the cars don’t make annoying grinding sounds. Overall, these bearings give my toy cars a professional, smooth rolling feel, and they’re a great value for the price. If you’re building small moving parts or toys, I definitely recommend these! Review: Absolute garbage. Inconsistent out of the packaging. Completely failed (locked up) in less than 24h of <60 RPM. You are better off burning your money. ## Features - MR128-2RS (I.D.=8mm, O.D.=12mm, Thickness=3.5mm) - mr128-2rs bearings are sealed on BOTH SIDES to keep lubricant in - Made from Chrome Steel (GCr15), durability and resistance to under heavy loads - ABEC Tolerance 1 (P0), Z2 Noise Level for most general use - Static load rating of 219 newtons and dynamic load rating of 462 newtons ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B082PPLHLQ | | ASIN | B082PPLHLQ | | Bearing Number | MR128-2RS | | Bearing Type | Ball Bearing | | Best Sellers Rank | #63,189 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #12 in Router Bearings | | Brand Name | uxcell | | Compatible Lubricant | Oil | | Customer Reviews | 4.7 4.7 out of 5 stars (128) | | Customer reviews | 4.7 4.7 out of 5 stars (128) | | Date First Available | 13 December 2019 | | Item Dimensions | 12 x 8 x 3 millimeters | | Item Thickness | 3.5 Millimeters | | Item Weight | 23 Grams | | Item model number | a19092000ux1288 | | Manufacturer | uxcell | | Manufacturer | uxcell | | Material Type | Alloy Steel | | Outside Diameter | 12 Millimeters | | Product Dimensions | 1.2 x 0.8 x 0.35 cm; 23 g | | Specification Met | ABEC 1 | ## Product Details - **Bearing number:** MR128-2RS - **Brand:** uxcell - **Item dimensions L x W x H:** 12 x 8 x 3 millimeters - **Item weight:** 23 Grams - **Material:** Alloy Steel ## Images ![uxcell MR128-2RS Deep Groove Ball Bearings 8mm Inner Dia 12mm OD 3.5mm Bore Double Sealed Chrome Steel Blue Seal Z2 10pcs - Image 1](https://m.media-amazon.com/images/I/61Oj-fYR-RL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***R on 13 July 2025* I use these uxcell MR128-2RS deep groove ball bearings in my kids’ 3D printed toy cars, and they work great!

Completely failed (locked up) in less than 24h of <60 RPM. You are better off burning your money. ### ⭐⭐⭐⭐⭐ Review *by R***G on 18 April 2025* If you own an AIPER Surfer S1 and the bearing are seized these work great. I have a salt water pool and the bearing seized after 6 months. These fit and work great. AIPER needs a new design. ## Frequently Bought Together - uxcell MR128-2RS Deep Groove Ball Bearings 8mm Inner Dia 12mm OD 3.5mm Bore Double Sealed Chrome Steel Blue Seal Z2 10pcs - uxcell 50pcs M2.5 X 8mm Stainless Steel Phillips Pan Round Head Self Tapping Screws - uxcell Fluorine Rubber O-Rings 24mm OD 19mm ID 2.5mm Width, Metric FKM Sealing Gasket, Pack of 20 --- ## 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.hr/products/552744571-uxcell-mr128-2rs-deep-groove-ball-bearings-8mm-inner-dia](https://www.desertcart.hr/products/552744571-uxcell-mr128-2rs-deep-groove-ball-bearings-8mm-inner-dia) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-17*
