6304-2RSH/C3GWF Bearing Product Overview & Core Advantages
The 6304-2RSH/C3GWF is a single row deep groove ball bearing designed for reliable performance in demanding applications. Engineered with metric dimensions and constructed from high-grade chrome steel, this bearing excels at handling radial loads efficiently. Its key advantages include robust construction, consistent operation within a wide temperature range of -30°C to 120°C, and compliance with industry standards including ROHS and REACH, making it a dependable choice for industrial machinery and equipment.
6304-2RSH/C3GWF Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 2RSH | Double Contact Seals (RS on both sides) | Provides superior protection against contamination and retains lubrication effectively. |
| C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion, suitable for applications with temperature variations or high speeds. |
| GW | Filling Slot (Not applicable for this sealed bearing) | Note: Typically used for relubrication in unsealed bearings. For 2RSH, the bearing is pre-lubricated and sealed for life. |
6304-2RSH/C3GWF Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and chrome steel construction provide excellent durability and consistent performance under radial dynamic load ratings up to 3574 lbf.
- Enhanced Sealing: The 2RSH double contact seals effectively shield the bearing interior from contaminants like dust and moisture, significantly extending service life in harsh environments.
- Optimized Internal Clearance: The C3 radial internal clearance allows for thermal expansion during operation, preventing binding and ensuring smooth running, particularly beneficial where operational temperatures may vary.
- Precision and Reliability: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing offers reliable performance for general industrial applications, ensuring consistent operation and long-term reliability.
