6306-2RS1/C3 GJN Bearing Product Overview & Core Advantages
The 6306-2RS1/C3 GJN is a sealed deep groove ball bearing engineered for demanding industrial applications. As a single row bearing, it offers a compact design capable of handling high radial loads and moderate axial loads in both directions. Its key advantages include the integrated contact seals (2RS1) for superior contamination exclusion and a greater than normal radial internal clearance (C3), making it exceptionally suitable for applications with thermal expansion or where shaft fits induce preload. This combination ensures high reliability and long service life in challenging environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6306 | Basic series number, indicating a medium series deep groove ball bearing with a 30mm bore and 72mm outside diameter. |
| 2RS1 | Bearing is fitted with two integral contact seals (one on each side) made from Nitrile Rubber (NBR), providing excellent protection against contaminants and moisture retention. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications involving thermal expansion, interference fits, or where minimal operational preload is desired. |
| GJN | Indicates the bearing is pre-lubricated with a high-quality, lithium-based grease. This grease offers a wide operating temperature range and is suitable for the majority of general industrial applications. |
6306-2RS1/C3 GJN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. With a dynamic load rating of 6002 lbf and a static load rating of 3372 lbf, it is built to withstand significant radial forces.
- Effective Sealing for Long Life: The 2RS1 contact seals effectively shield the internal components from dust, dirt, and moisture, while retaining the factory-applied grease. This significantly extends the bearing's service life and reduces maintenance needs.
- Optimized Internal Clearance: The C3 clearance provides operational flexibility, preventing excessive preload and potential overheating in applications with shaft expansion or heavy press fits, thereby enhancing reliability.
- Ready-to-Install Convenience: The bearing is supplied pre-lubricated (GJN) and sealed, making it a maintenance-free solution that is immediately ready for installation, saving time and resources.
