6308-2RS1/C3WT Bearing Product Overview & Core Advantages
The 6308-2RS1/C3WT is a single row deep groove ball bearing designed for robust performance and long service life. This sealed bearing excels in applications requiring reliable operation under radial loads. Its key advantages include the integration of contact seals (2RS1) for superior contamination exclusion and a C3 radial internal clearance for stable operation in applications with thermal expansion or heavy loads. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers dependable precision for a wide range of industrial uses.
6308-2RS1/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6308 | Standard designation for a single row deep groove ball bearing with a 40mm bore. | Defines the core bearing dimensions and type. |
| 2RS1 | Bearing is fitted with two contact seals, one on each side. | Provides excellent protection against contaminants like dust and moisture, retaining lubricant for extended service life. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Accommodates thermal expansion in the shaft and housing, making it suitable for applications with heavy loads or elevated operating temperatures. |
| WT | Indicates the bearing is supplied without lubrication. | Allows for application-specific lubrication or use in environments where standard greases are not suitable. |
6308-2RS1/C3WT Bearing Structural Features & Performance Benefits
Deep Groove Raceway & High-Quality Components: The optimized deep groove geometry on both inner and outer rings enables the bearing to handle not only significant radial loads but also moderate axial loads in both directions. All components, including the rings, balls, and cage, are manufactured from high-grade Chrome Steel, ensuring high strength, durability, and resistance to wear.
Robust Sealing Solution: The 2RS1 contact seals are a critical feature, effectively shielding the internal components from contaminants. This design significantly extends the bearing's operational life by preventing premature failure and maintaining performance integrity in harsh environments.
Optimized Internal Clearance: The C3 clearance is a key performance feature. It prevents excessive preloading and potential seizure that can occur due to thermal expansion during operation or from tight-fitting housings, ensuring reliable performance under demanding conditions.
6308-2RS1/C3WT Bearing Typical Application Areas
The 6308-2RS1/C3WT is a versatile component suited for a broad spectrum of industrial machinery and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
