6322 MA/C3B20 Bearing Product Overview & Core Advantages
The 6322 MA/C3B20 is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This open-type bearing features a robust construction with a C3 radial internal clearance, making it ideally suited for applications where thermal expansion is a consideration. Its high radial dynamic and static load ratings ensure reliable operation under significant stress, while the machined metal cage provides stability at high rotational speeds. Engineered for precision and durability, this bearing is a cornerstone component for systems requiring dependable radial load support.
6322 MA/C3B20 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6322 | Standard bearing series designation, indicating a metric single row deep groove ball bearing with a 110mm bore. |
| MA | Indicates a machined brass cage, providing high strength, excellent guidance, and suitability for high-speed applications. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications with expected thermal expansion, preventing preload and ensuring smooth operation. |
| B20 | This suffix is not a standard universal code for this bearing type and may represent a manufacturer-specific designation. It is recommended to consult the manufacturer's datasheet for precise interpretation. |
6322 MA/C3B20 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove raceway and chrome steel construction provide high radial dynamic and static load ratings (45636 lbf / 40466 lbf), ensuring stable performance under heavy loads.
- Optimized for High Speeds: The machined brass (MA) cage offers superior strength and reduced friction, contributing to a high limiting speed of 5,300 rpm.
- Thermal Stability: The C3 radial internal clearance accommodates dimensional changes due to thermal expansion in the shaft or housing, preventing binding and premature failure.
