6312-RS1Z/C4GJN4 Bearing Product Overview & Core Advantages
The 6312-RS1Z/C4GJN4 is a single row deep groove ball bearing engineered for high-performance applications requiring reliable radial load capacity and effective sealing. This metric bearing features one side shielded and one side sealed configuration, providing superior contamination protection while maintaining operational efficiency. Manufactured to ABEC 1 | ISO P0 tolerance standards with C4 radial internal clearance, it delivers consistent precision and stable operation across diverse industrial environments. Its balanced design supports high rotational speeds up to 5,300 rpm while maintaining structural integrity under substantial dynamic loads.
6312-RS1Z/C4GJN4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| RS1 | One side contact seal (rubber) | Effective protection against contaminants and moisture ingress |
| Z | One side shielded (metal) | Robust physical barrier with minimal friction increase |
| C4 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
| GJN4 | Polyurea grease, temperature range -30°C to +120°C | Extended lubrication intervals and wide temperature compatibility |
6312-RS1Z/C4GJN4 Bearing Structural Features & Performance Benefits
Optimized Sealing System: The combination of metal shield on one side and contact seal on the other provides comprehensive protection against contaminants while maintaining excellent rotational performance. This dual-sealing approach extends bearing service life in challenging environments.
Enhanced Load Capacity: With a radial dynamic load rating of 18,412 lbf and static load rating of 11,735 lbf, this bearing delivers reliable performance under substantial radial loads. The deep groove raceway design ensures optimal stress distribution.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing offers superior hardness and wear resistance. The integrated steel cage provides stable ball guidance and maintains proper ball spacing at high speeds.
Thermal Management: The C4 radial clearance accommodates differential thermal expansion between shaft and housing, preventing premature failure in applications with significant temperature variations.
