| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 2RS1 | Double Contact Seals | Provides superior **contamination protection** and **lubricant retention** |
| NR | Snap Ring Groove | Enables **easy axial positioning** and **simplified assembly** |
| C3 | Greater Radial Clearance | Accommodates **thermal expansion** and prevents seizure |
| W64 | Solid Oil Lubrication | Ensures **consistent lubrication** and **maintenance-free operation** |
6305-2RS1NR/C3W64 Bearing Structural Features & Performance Benefits
Enhanced Sealing System: The double-contact rubber seals (2RS1) provide exceptional protection against contaminants while effectively retaining lubrication, significantly extending **bearing service life** in harsh environments.
Optimized Internal Clearance: With **C3 radial clearance**, this bearing accommodates differential thermal expansion between shaft and housing, preventing **preload conditions** and ensuring smooth operation across varying temperature conditions.
Advanced Lubrication Technology: The **Solid Oil W64** filling replaces traditional grease, eliminating leakage and providing consistent lubrication throughout the bearing's operational life, even at the maximum **limiting speed** of 11,000 rpm.
Installation Efficiency: The integrated **snap ring groove** simplifies axial positioning and reduces assembly time, while the **ABEC 1 precision** ensures reliable performance for general industrial applications.
