6306-2ZNR/C3 Bearing Product Overview & Core Advantages
The 6306-2ZNR/C3 is a single row deep groove ball bearing engineered for high-performance industrial applications. This shielded bearing features an integral snap ring on its outer ring, enabling simplified axial location within housings without requiring complex machining. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used. Designed to handle primarily radial loads, this precision bearing offers reliable operation across a wide temperature range from -30°C to 120°C, making it an optimal choice for demanding industrial environments requiring high reliability and ease of installation.
Model Code Detailed Explanation
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 6306 | Basic bearing designation (30mm bore, 72mm OD) | Standard bearing dimensions for compatibility |
| 2Z | Non-contact shields on both sides | Effective contamination protection with minimal speed reduction |
| NR | Snap ring groove and snap ring on outer ring | Simplified axial positioning and reduced assembly costs |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits |
6306-2ZNR/C3 Bearing Structural Features & Performance Benefits
Enhanced Sealing Protection: The 2Z non-contact shields provide superior protection against contaminants while maintaining high rotational capabilities, extending bearing service life in challenging environments.
Simplified Mounting Solution: The integrated snap ring (NR designation) eliminates the need for complex housing shoulders or separate retaining devices, reducing assembly time and manufacturing costs while ensuring secure axial location.
Optimized Internal Clearance: The C3 radial clearance provides additional internal space to accommodate thermal expansion in high-temperature applications or compensate for tight interference fits, preventing premature failure due to excessive preload.
Robust Construction: Manufactured from chrome steel for all critical components (rings, balls, cage), this bearing delivers consistent performance under radial dynamic loads up to 6002 lbf and static loads up to 3372 lbf.
Precision Engineering: Built to ABEC 1 | ISO P0 tolerance class, this bearing ensures reliable operation with dimensional consistency critical for industrial applications.
