6309-ZN/C3HT51 Bearing Product Overview & Core Advantages
The 6309-ZN/C3HT51 is a single row deep groove ball bearing engineered for robust performance in demanding applications. This metric bearing features a shielded design and a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Its high radial dynamic load rating of 11,915 lbf and precision ABEC 1 | ISO P0 tolerance ensure reliable operation and long service life. The inclusion of a snap ring groove on the outer ring facilitates secure and simplified axial location within a housing, enhancing mounting stability.
Model Code Breakdown
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| Z | Shield on one side | Protects against contaminants from one direction. |
| N | Snap ring groove on the outer ring | Enables secure axial positioning, simplifying housing design. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits, preventing premature failure. |
| HT51 | High-temperature grease | Ensures stable lubrication and performance within the specified temperature range of -30°C to 120°C. |
6309-ZN/C3HT51 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for both rings, balls, and cage, this bearing offers excellent durability and a high radial dynamic load rating, making it ideal for applications with significant radial loads.
- Optimized for Stability: The snap ring groove (N) feature provides a positive locating method, increasing the system's rigidity and simplifying assembly.
- Enhanced Operational Reliability: The C3 clearance is crucial for applications prone to thermal expansion, ensuring consistent performance without binding. The shield (Z) offers a degree of contamination protection, while the HT51 grease provides reliable lubrication across a wide temperature range, contributing to a long, maintenance-free service life.
- Precision Performance: Built to ABEC 1 | ISO P0 tolerance standards, this bearing ensures smooth and quiet operation, suitable for a wide range of industrial machinery.
