6308/C3S1 Bearing Product Overview & Core Advantages
The 6308/C3S1 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This metric bearing is characterized by its robust radial load capacity and versatility. Its open design allows for easy re-lubrication and customization, while the specified C3 radial internal clearance makes it ideal for applications with thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable precision and high operational reliability, making it a fundamental component for a wide range of machinery.
6308/C3S1 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6308 | Basic designation indicating a medium series, single row deep groove ball bearing with a 40mm bore. | Defines the core bearing dimensions and type. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Accommodates thermal expansion in the shaft or housing, preventing preload and ensuring smooth operation in high-temperature or high-speed applications. |
| S1 | Indicates the bearing is stabilized for continuous operation at elevated temperatures up to 200°C. | Ensures dimensional stability and maintains performance in high-temperature environments. |
6308/C3S1 Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 915 lbf and a radial static load rating of 5395 lbf, ensuring durability under significant stress.
- Optimized for Thermal Conditions: The C3 internal clearance is a critical feature that prevents binding and reduces friction when the bearing operates at elevated temperatures or is mounted with tight fits, contributing to a longer service life.
- High-Temperature Stability: The S1 heat stabilization treatment allows the bearing to maintain its dimensional integrity and mechanical properties across a wide temperature range from -30°C to 200°C.
- Versatile & Customizable: The open seal type provides flexibility, allowing for the application of specialized lubricants tailored to specific operational needs, such as high-speed or extreme environment applications.
6308/C3S1 Bearing Typical Application Areas
This bearing is a workhorse component suitable for a broad spectrum of industrial machinery, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring robust and reliable ball bearing support.
