6203-2RSH/C3GJN Bearing Product Overview & Core Advantages
The 6203-2RSH/C3GJN is a metric single row deep groove ball bearing engineered for high performance and reliability in demanding applications. Its core advantages stem from its sealed design and optimized internal geometry, enabling it to handle significant radial loads and moderate axial loads in both directions. The bearing is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and smooth operation. Pre-lubricated and sealed for life, it offers a maintenance-free solution ideal for applications requiring long service intervals and high operational reliability.
6203-2RSH/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Basic bearing series and size designation (17mm bore, 40mm OD, 12mm width). |
| 2RS | Contact seals on both sides, providing superior protection against contaminants and retaining lubricant. |
| H | Indicates the use of a special heat-stabilized cage material, enhancing dimensional stability at elevated temperatures. |
| C3 | Greater than normal radial internal clearance, suitable for applications with thermal expansion or where interference fits are used. |
| GJN | Specifies a polyurea grease filling. This grease offers excellent performance over a wide temperature range and provides long-term lubrication. |
6203-2RSH/C3GJN Bearing Structural Features & Performance Benefits
- Robust Sealing & Longevity: The double-sided contact seals (2RS) effectively shield the bearing's interior from dust, moisture, and other contaminants while securely retaining the high-performance GJN polyurea grease. This combination creates a maintenance-free system with an extended service life.
- Optimized Load Capacity: The deep groove raceway and high-quality chrome steel construction enable the bearing to support high radial dynamic load ratings of 2147 lbf, as well as moderate axial loads.
- Thermal & Dimensional Stability: The heat-stabilized cage (H) ensures consistent performance and prevents cage distortion at the upper end of the operating temperature range (-30°C to 120°C), contributing to smooth running at the limiting speed of 17,000 rpm.
- Operational Flexibility: The C3 radial internal clearance accommodates thermal expansion in the shaft and housing, making it suitable for applications where temperature differentials are expected or where tight interference fits are employed.
6203-2RSH/C3GJN Bearing Typical Application Areas
The 6203-2RSH/C3GJN is ideally suited for a wide range of industrial machinery and equipment requiring reliable, sealed, and maintenance-free operation. Key application areas include:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor System Pulleys and Idlers
- Agricultural Machinery
