6308-2RS1/GJN Bearing Product Overview & Core Advantages
The 6308-2RS1 is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its core advantage lies in its versatile load capacity, effectively handling both radial loads and moderate axial loads in both directions. The integrated 2RS1 rubber seals on both sides provide excellent protection against contamination, making this bearing a robust and maintenance-friendly solution for demanding environments. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent and dependable operation.
Model Code In-Depth Analysis
| Code Segment | Technical Meaning |
|---|---|
| 6308 | Basic series designation for a medium-duty, single row deep groove ball bearing with a 40mm bore and 90mm outside diameter. |
| 2RS1 | Indicates the bearing is equipped with contact rubber seals on both sides. These seals offer superior protection against dust and moisture compared to non-contact shields. |
| /GJN | This suffix denotes that the bearing is pre-lubricated with a specific polyurea grease suitable for a standard temperature range of -30°C to +120°C. |
6308-2RS1/GJN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. With a radial dynamic load rating of 915 lbf and a static load rating of 5395 lbf, it is engineered to handle significant radial loads effectively.
- Effective Sealing for Long Service Life: The 2RS1 rubber seals are the key to its longevity. By effectively excluding contaminants and retaining grease, they significantly extend the bearing's operational life and reduce the need for maintenance, making it ideal for dirty or humid environments.
- Optimized for Standard Applications: The combination of CN radial internal clearance and ABEC 1 precision provides an excellent balance for general industrial use, ensuring smooth operation and reliable performance without the cost of ultra-high precision.
- Ready-to-Install Convenience: Pre-lubricated with GJN grease, the bearing is delivered ready for immediate installation, simplifying the assembly process and ensuring proper lubrication from the first rotation.
