6309 M4A/C3 Bearing Product Overview & Core Advantages
The 6309 C3 is a single row deep groove ball bearing designed for robust performance in general industrial applications. This metric bearing excels at handling primarily radial loads and offers high operational reliability. Its key advantages include a generous C3 radial internal clearance, making it exceptionally suitable for applications involving thermal expansion or where interference fits are used, ensuring consistent performance under varying operational conditions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution without compromising on essential precision and durability.
6309 M4A/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6309 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 45mm bore, 100mm OD, and 25mm width. |
| C3 | Radial Internal Clearance | Indicates a greater than normal radial internal clearance. This is critical for applications with shaft misalignment, high-speed operations, or where significant temperature variations are expected, preventing premature bearing failure. |
6309 M4A/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: The single row deep groove raceway and machined metal cage provide stable guidance for the balls, enabling high radial dynamic load rating of 12,432 lbf and a radial static load rating of 7,081 lbf. This ensures reliable operation under significant loads.
- Optimized for Demanding Environments: The C3 clearance is a key structural feature that accommodates dimensional changes from heat or press-fits, maintaining optimal performance and extending service life in challenging conditions.
- High-Speed Capability: With a limiting speed of 14,000 rpm, the precision-ground chrome steel components and robust cage design minimize friction and centrifugal forces, making it suitable for a wide range of operational speeds.
- Versatile Application Readiness: The open seal type allows for easy re-lubrication and custom lubrication schemes, while the standard ABEC 1 (ISO P0) tolerance guarantees consistent and reliable performance for most industrial uses.
