Product Overview and Core Advantages
The 6318-2Z/C3GJN is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. Engineered with shielded protection (2Z) on both sides, it effectively prevents contaminant ingress while retaining lubrication. Featuring an increased radial internal clearance (C3), this bearing is optimally suited for applications with thermal expansion concerns or where interference fits are used. Its high radial dynamic load capacity of 32,148 lbf ensures reliable operation under significant stress, making it an excellent choice for general machinery requiring durable and maintenance-friendly components.
6318-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| -2Z | Steel shields on both sides | Provides effective contamination protection while allowing for higher speed operation compared to contact seals |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in shafts and housings, ideal for applications with temperature variations or interference fits |
| GJN | Grease type designation | Indicates specific high-quality grease filling for extended service life and reliable performance |
Structural Features and Performance Benefits
This bearing's construction delivers distinct performance advantages:
- Optimized Load Distribution: The single row deep groove raceway geometry enables smooth operation under high radial loads while accommodating moderate axial loads in both directions
- Enhanced Durability: Manufactured from chrome steel for both rings and balls, ensuring excellent wear resistance and fatigue strength
- Precision Engineering: Built to ABEC 1 | ISO P0 tolerance class, providing consistent dimensional accuracy for reliable performance in general industrial applications
- Thermal Compensation: The C3 clearance accommodates dimensional changes due to temperature fluctuations, preventing premature failure in variable temperature environments
- Maintenance Efficiency: Factory-applied grease lubrication (GJN) combined with shielded design creates a virtually maintenance-free solution for the bearing's service life
