You’ll often find them on rapidly rotating parts, from the whirring chuck on a power drill to the spinning shaft on an electric motor. - DOUBLE SHIELDED: Double Shielded closures have a shield on both sides to protect the rolling elements from dust and debris, but allow lubricants to get in. Shields are made of metal and are not limited by speed or high temperature conditions. - BEARING STEEL: Bearing steel cage material is durable and wear resistant in applications where corrosion is not a concern. Bearing steel ring material resists corrosion when exposed to damp or harsh environments. - APPLICATIONS: Radial ball bearings provide support and alignment for rotary motion elements to run smoothly, such as a wheel on an axle. Ball bearings reduce friction which causes noise, vibration, and wear. They are found in a wide variety of equipment that have rotary motion elements such as in machine tools, pumps, motors, and conveyors. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07M7H7RBC | | Bearing Number | MR128ZZ | | Bearing Type | Ball Bearing | | Brand Name | CNBTR | | Compatible Lubricant | Grease | | Customer Reviews | 4.6 4.6 out of 5 stars (259) | | Included Components | 10 x Mini Ball Bearings | | Item Highlight | 3.5 mm Outer Ring Width | Double Shielded | Bearing Steel Ring | Ideal for Machine Tools, Fans, Pumps, Motors, and Conveyors | | Item Thickness | 2.5 millimeters | | Item Weight | 1 g | | Manufacturer | YQLTD | | Material Type | Alloy Steel | | Model | M6190101158 | | Number of Items | 10 | | Number of Packs | 1 | | Outside Diameter | 5 millimeters | | Part Number | M6190101158 | | Specification Met | Mr128zz | | Unit Count | 10 Count | ## Product Details - **Bearing Number:** MR128ZZ - **Brand:** CNBTR - **Item Thickness:** 2.5 millimeters - **Item Weight:** 1 g - **Material:** Alloy Steel ## Images ![10PCS Miniature Radial Ball Bearings | 8 mm Bore Diameter | 12 mm OD - Image 1](https://m.media-amazon.com/images/I/41oC1pXicRL.jpg) ![10PCS Miniature Radial Ball Bearings | 8 mm Bore Diameter | 12 mm OD - Image 2](https://m.media-amazon.com/images/I/41kqwYW2SxL.jpg) ![10PCS Miniature Radial Ball Bearings | 8 mm Bore Diameter | 12 mm OD - Image 3](https://m.media-amazon.com/images/I/41Z2MdsnW3L.jpg) ![10PCS Miniature Radial Ball Bearings | 8 mm Bore Diameter | 12 mm OD - Image 4](https://m.media-amazon.com/images/I/41gG1g4AwOL.jpg) ![10PCS Miniature Radial Ball Bearings | 8 mm Bore Diameter | 12 mm OD - Image 5](https://m.media-amazon.com/images/I/41ckUnAZZlL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - CNBTR 8mm ID 12mm OD 3.5mm Thickness Bearing Steel Mini Groove Ball Bearings DIY Industry MR128ZZ Pack of 10 - Arduino Nano Every [ABX00028] – ATmega4809, 48KB Flash, 6KB SRAM, 20 Digital I/O, 8 Analog Inputs, Micro USB Type-B, Compatible with Arduino IDE for Embedded Projects --- ## 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.jp/products/148772598-10pcs-miniature-radial-ball-bearings-8-mm-bore-diameter-12](https://www.desertcart.jp/products/148772598-10pcs-miniature-radial-ball-bearings-8-mm-bore-diameter-12) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-18*
