6212 MA/C3 Bearing Product Overview & Core Advantages
The 6212 MA/C3 is a high-performance single row deep groove ball bearing engineered for demanding industrial applications. This metric bearing is characterized by its robust radial load capacity and optimized internal geometry, making it a reliable choice for general machinery. Its C3 radial internal clearance is specifically designed for applications with elevated operational temperatures or where interference fits are used, ensuring stable performance under such conditions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers excellent cost-effectiveness for a wide range of precision engineering requirements.
6212 MA/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6212 | Standard bearing series designation, indicating a single row deep groove ball bearing with a 60 mm bore and 110 mm OD. |
| MA | Indicates a machined brass cage, offering high strength, excellent guidance, and suitability for high-speed operation and demanding conditions. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications involving thermal expansion, heavy loads, or interference fits to prevent premature failure. |
6212 MA/C3 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of the machined brass (MA) cage and deep groove raceway geometry enables smooth operation at high rotational speeds, with a limiting speed of 11,000 rpm.
- Robust Load Handling: With a dynamic load rating of 12,432 lbf and a static load rating of 8,093 lbf, this bearing is built to handle significant radial loads in continuous operation.
- Thermal & Fit Adaptability: The C3 clearance is a key feature that accommodates dimensional changes from heat generation and shaft/housing fits, preventing binding and ensuring operational reliability.
- Durability and Precision: Constructed from chrome steel for both rings and balls, and manufactured to ABEC 1 precision, it provides long service life and consistent performance in a variety of industrial environments.
