Product Overview and Core Advantages
The 6308-2RS1/C3W64 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing excels at handling primarily radial loads and offers robust performance due to its optimized internal geometry. A key advantage is its Solid Oil lubrication and C3 radial internal clearance, making it suitable for applications with thermal expansion or requiring high operational stability. Its construction ensures long service life and consistent performance, positioning it as a versatile and durable solution for industrial machinery.
6308-2RS1/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| -2RS1 | Contact seals on both sides made from NBR | Provides excellent protection against contaminants and retains lubricant effectively. |
| /C3 | Radial internal clearance greater than Normal (CN) | Accommodates thermal expansion in the shaft or housing, preventing preload and ensuring smooth operation. |
| W64 | Solid Oil lubrication | Offers a maintenance-free solution with consistent lubrication, even in challenging environments, and is suitable for a wide temperature range. |
Structural Features and Performance Benefits
The performance of the 6308-2RS1/C3W64 is derived from its specific design features. The single row deep groove raceway is precision-ground to handle high radial dynamic load ratings efficiently. The contact seals (2RS1) are a critical feature, providing a robust barrier against dust, moisture, and other contaminants, which significantly enhances bearing life in harsh conditions. The integration of Solid Oil (W64) eliminates the need for re-lubrication, providing a consistent lubricating film that reduces wear and friction. Combined with the C3 clearance, this bearing is exceptionally well-suited for applications where operational temperatures fluctuate, preventing binding and maintaining optimal performance. The use of chrome steel for all critical components ensures high strength and durability.
