6303-2RSH/C3GWF Bearing Product Overview & Core Advantages
The 6303-2RSH/C3GWF is a single row deep groove ball bearing designed for robust performance in demanding applications. Its primary strength lies in its ability to efficiently handle radial loads while offering operational reliability. This bearing features integral seals (2RSH) for superior contamination protection and is supplied pre-lubricated. Manufactured to ABEC 1 (ISO P0) tolerance standards with a C3 radial internal clearance, it is an excellent choice for applications requiring consistent performance under varying thermal conditions.
6303-2RSH/C3GWF Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6303 | Basic bearing series and size designation (17mm bore, 47mm OD, 14mm width). |
| 2RSH | Contact seals on both sides, made of NBR rubber, offering excellent protection against contaminants and moisture. |
| C3 | Radial internal clearance greater than normal (CN), suitable for applications with thermal expansion or where interference fits are used. |
| GWF | Indicates the bearing is supplied with a standard lithium-based grease suitable for a wide temperature range. |
6303-2RSH/C3GWF Bearing Structural Features & Performance Benefits
- Sealed and Pre-lubricated Design: The 2RSH contact seals provide a high degree of protection, making the bearing suitable for dirty or humid environments. Being factory-filled with grease enables immediate start-up and offers long-term, maintenance-free operation.
- Optimized Internal Geometry: The deep groove raceway and high-quality chrome steel construction ensure smooth operation and a high dynamic load rating of 3057 lbf, providing a long service life.
- Thermal Stability: The specified C3 clearance accommodates differential thermal expansion between the inner and outer rings, preventing preload and potential seizure in applications with significant temperature fluctuations.
- Standard Precision: Manufactured to ABEC 1 (ISO P0) tolerance class, this bearing delivers reliable and consistent performance for general industrial applications.
6303-2RSH/C3GWF Bearing Typical Application Areas
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
