6228 MA/C4 Bearing Product Overview & Core Advantages
The 6228 MA/C4 is a single row deep groove ball bearing engineered for demanding industrial applications. This open-type bearing is designed to primarily accommodate high radial loads, offering reliable performance and long service life. A key feature is its C4 radial internal clearance, which makes it particularly suitable for applications with significant thermal expansion or where interference fits are used, ensuring optimal performance under varying operational conditions. Manufactured from high-grade chrome steel with a robust machined metal cage, it delivers excellent durability and operational stability.
6228 MA/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| MA | Machined Brass Cage | Indicates the use of a high-strength, machined brass cage, which provides superior guidance, stability, and is suitable for high-speed applications. |
| C4 | Radial Internal Clearance greater than Normal | Specifies a larger than standard radial internal clearance. This is critical for applications involving thermal expansion, heavy interference fits, or where operational heat generation is significant. |
