6308-2RS1/C3GJN Bearing Product Overview & Core Advantages
The 6308-2RS1/C3GJN is a metric single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Its key advantage lies in its ability to efficiently handle radial loads while offering reliable operation. The bearing features integrated seals (2RS1) for effective contamination exclusion and is supplied pre-lubricated, ensuring immediate readiness for installation and contributing to a long service life. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides dependable precision for general machinery, making it an excellent choice for applications demanding high reliability and durability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6308 | Basic series designation for a medium-duty, single row deep groove ball bearing with a 40mm bore. |
| -2RS1 | Indicates the bearing is fitted with two rubber contact seals (RS1), one on each side, providing excellent protection against contaminants and retention of lubricant. |
| /C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with thermal expansion or where interference fits are used. |
| GJN | Indicates the bearing is pre-lubricated with a specific, high-quality grease suitable for the standard operating temperature range. |
6308-2RS1/C3GJN Bearing Structural Features & Performance Benefits
- Sealed Design for Enhanced Reliability: The 2RS1 rubber contact seals effectively shield the internal components from dust, moisture, and other contaminants. This significantly extends the bearing's operational life and reduces the need for maintenance, making it suitable for dirty or humid environments.
- Optimized Internal Clearance: The C3 radial internal clearance provides operational stability in applications where bearing rings are subjected to different thermal expansions or heavy interference fits, preventing premature failure due to excessive preload.
- Robust Load Capacity: The single row deep groove construction is engineered to support significant radial dynamic and static loads (915 lbf and 5395 lbf respectively), ensuring reliable performance under demanding conditions.
- Ready-to-Install Convenience: The bearing is supplied pre-lubricated (GJN), which simplifies installation and provides immediate protection against wear from the first moment of operation.
6308-2RS1/C3GJN Bearing Typical Application Areas
The 6308-2RS1/C3GJN is a versatile component widely used across various industries due to its sealed and pre-lubricated design. Common applications include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., Conveyor Pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial support
