6228 MA/C3 Bearing Product Overview & Core Advantages
The 6228 MA/C3 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This open-type bearing is engineered to primarily handle radial loads and offers a high limiting speed. Its key advantages include a high radial dynamic load rating of 37,093 lbf, reliable operation within a wide temperature range of -30°C to 120°C, and a C3 radial internal clearance suitable for applications with thermal expansion or heavy interference fits. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent performance and high reliability.
6228 MA/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6228 | Basic bearing designation indicating a Metric series, 140mm bore, 250mm OD, and 42mm width. |
| MA | Indicates a machined brass cage (cage material). This cage design offers high strength and is suitable for high-speed applications and demanding operating conditions. |
| C3 | Specifies a greater radial internal clearance than the standard C0 group. This is essential for applications where thermal expansion, shaft interference fits, or heavy loads are present, preventing premature bearing failure due to excessive preload. |
6228 MA/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove construction with chrome steel rings and balls provides excellent resistance to radial loads. The high dynamic and static load ratings ensure long service life under significant stress.
- Optimized for High-Speed Operation: The machined brass (MA) cage provides superior guidance and stability for the balls, contributing to a high limiting speed of 3,400 rpm. This makes it suitable for applications requiring rapid rotation.
- Operational Versatility with C3 Clearance: The C3 radial internal clearance allows for thermal expansion of the inner ring and shaft, making this bearing ideal for applications with elevated operating temperatures or where tight interference fits are used, preventing binding and reducing friction.
- Broad Application Temperature Range: Constructed from high-quality chrome steel, the bearing maintains dimensional stability and performance across a wide temperature range from -30°C to 120°C.
6228 MA/C3 Bearing Typical Application Areas
This bearing is commonly specified in industries and equipment requiring reliable performance under radial loads and moderate to high speeds, including:
- Industrial Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Industrial Pumps and Fans
