6303-2RSH/C3GJN Bearing Product Overview & Core Advantages
The 6303-2RSH/C3GJN is a single row deep groove ball bearing engineered for high reliability in demanding applications. This sealed bearing is designed to accommodate significant radial loads and moderate axial loads in both directions. Its key advantages include a robust C3 radial internal clearance for thermal expansion management in high-speed or high-temperature environments, and integral contact seals (2RSH) that provide superior protection against contaminants. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and is pre-lubricated for long service life, making it an excellent choice for a wide range of industrial machinery.
6303-2RSH/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6303 | Standard bearing series designation (17mm bore, 47mm OD, 14mm width). | Defines the core bearing dimensions and basic dynamic load capacity. |
| 2RSH | Contact seals on both sides, made of NBR (Nitrile Butadiene Rubber). | Provides excellent protection against dust, dirt, and moisture ingress, enhancing bearing longevity. |
| C3 | Greater than normal radial internal clearance. | Accommodates shaft expansion under high-speed or high-temperature conditions, preventing premature failure. |
| GJN | Specifies the type of polyurea grease used for pre-lubrication. | Offers a wide temperature range (-30°C to +120°C), excellent oxidation stability, and long-term lubrication. |
6303-2RSH/C3GJN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high radial dynamic load rating of 3057 lbf. Its single row deep groove raceway geometry is optimized to handle significant radial loads and combined loads efficiently.
- Optimized for Challenging Environments: The C3 radial clearance is a critical feature for applications prone to thermal expansion, ensuring stable operation and preventing internal preload that can lead to overheating and reduced limiting speed (15,000 rpm).
- Enhanced Sealing & Maintenance-Free Operation: The 2RSH contact seals provide a superior barrier compared to non-contact shields, effectively retaining grease and excluding contaminants. Combined with the long-life polyurea grease (GJN), this design ensures reliable, maintenance-free operation over extended periods.
- Precision & Consistency: Adherence to ABEC 1 | ISO P0 tolerance class guarantees dimensional accuracy and running precision, contributing to smooth operation, low vibration, and predictable performance in a variety of machinery.
6303-2RSH/C3GJN Bearing Typical Application Areas
This versatile deep groove ball bearing is ideally suited for a multitude of industrial applications requiring reliable performance under radial loads, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- Automotive Components (Alternators, Idlers)
