| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2RS | Contact seals on both sides | Provides excellent protection against contaminant ingress and retains lubricant effectively. |
| NR | Snap ring groove on the outer ring | Facilitates easy axial location and secure mounting, simplifying assembly and reducing housing design complexity. |
6306-2RSNR Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built with chrome steel rings, balls, and cage, this bearing offers a high dynamic load rating of 6002 lbf and a static load rating of 3372 lbf, ensuring durability under significant radial loads.
- Sealed & Pre-lubricated Design: The integral contact seals (2RS) shield the bearing from dust, moisture, and other contaminants while retaining the factory-applied lubricant. This creates a maintenance-free system ideal for applications where re-lubrication is difficult.
- Simplified Mounting with Snap Ring: The outer ring snap ring groove allows for secure axial positioning without the need for complex housing shoulders or end caps, reducing assembly time and cost.
- Consistent Performance: Manufactured to ABEC 1 precision with standard CN radial internal clearance, the bearing provides smooth operation and reliable performance across its specified temperature range of -30°C to 120°C.
6306-2RSNR Bearing Typical Application Areas
This versatile bearing is commonly specified in a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
