6304-2RS1/C3 GJN Bearing Product Overview & Core Advantages
The 6304-2RS1/C3 GJN is a sealed single row deep groove ball bearing engineered for high reliability in demanding applications. This metric bearing is designed to accommodate primarily radial loads and moderate axial loads in both directions. Its key advantages include a robust sealed construction for contaminant exclusion, an optimized C3 radial internal clearance for thermal expansion management in operational environments, and compliance with ABEC 1 | ISO P0 tolerance standards for consistent performance. The combination of chrome steel components ensures high durability and a long service life.
Model Code Breakdown
| Suffix Code | Technical Meaning |
|---|---|
| -2RS1 | Designates contact seals made of NBR (Nitrile Rubber) on both sides. This provides effective protection against contaminants and moisture retention. |
| /C3 | Indicates a greater radial internal clearance than the Normal (CN) group. This is essential for applications with significant thermal gradients or where interference fits are used. |
| GJN | Signifies the bearing is pre-lubricated with a high-quality polyurea grease. This grease offers excellent performance across the specified temperature range and contributes to the bearing's maintenance-free characteristics. |
6304-2RS1/C3 GJN Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The double-sided contact seals (2RS1) create an effective barrier against dust, dirt, and moisture, significantly enhancing bearing life in contaminated environments. The seals also help retain the factory-applied grease.
- Optimized Internal Clearance: The C3 radial clearance is a critical feature for applications where operational heat causes shaft and housing expansion. It prevents excessive preload and potential bearing seizure, ensuring smooth operation.
- High-Quality Material & Construction: Manufactured from chrome steel for rings, balls, and cage, this bearing offers high load capacity, excellent wear resistance, and long-term dimensional stability.
- Ready-to-Use & Maintenance-Free: The bearing is supplied pre-lubricated with GJN grease, making it immediately ready for installation. This, combined with the effective seals, eliminates the need for re-lubrication in many applications, reducing maintenance costs.
6304-2RS1/C3 GJN Bearing Typical Application Areas
This versatile bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
