E2 6003-2RSH/C3 Bearing Product Overview & Core Advantages
The E2 6003-2RSH/C3 is a sealed single row deep groove ball bearing engineered for reliable performance in demanding applications. This metric bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a robust balance of precision and durability. Its sealed construction and C3 radial internal clearance make it an excellent choice for applications requiring protection from contaminants and stable operation under varying thermal conditions.
E2 6003-2RSH/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| E2 | Manufacturer's internal designator for optimized performance. |
| 6003 | Standard bearing series designation, indicating a deep groove geometry with a 17mm bore, 35mm OD, and 10mm width. |
| 2RSH | Features two contact seals (RSH type) on both sides. These high-performance seals provide superior protection against contaminants and moisture retention compared to standard seals. |
| C3 | Indicates a greater than normal radial internal clearance. This is beneficial for applications with thermal expansion or where interference fits are used, preventing preload and ensuring smooth operation. |
E2 6003-2RSH/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built entirely from chrome steel for rings, balls, and cage, this bearing delivers high strength and wear resistance. With a dynamic load rating of 1349 lbf and a static load rating of 731 lbf, it is designed for long service life under substantial radial loads.
- Enhanced Sealing for Reliability: The 2RSH contact seals effectively shield the internal components from dust, dirt, and other contaminants, while also retaining lubrication. This results in a maintenance-free and long-lasting solution, reducing downtime.
- Optimized for Thermal & Speed Conditions: The C3 clearance accommodates shaft expansion and interference fits, preventing binding at high operating temperatures. This contributes to stable performance up to the limiting speed of 21,000 rpm.
- Broad Operating Range: The bearing is suitable for a temperature range from -30°C to 120°C, making it versatile for various industrial environments.
E2 6003-2RSH/C3 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of applications where reliability and contamination protection are critical. Key sectors include:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery and Power Tools
- Various Automotive Components (e.g., alternators, idler pulleys)
