6203-2RSH/C3HT Bearing Product Overview & Core Advantages
The 6203-2RSH/C3 is a single row deep groove ball bearing designed for exceptional reliability and performance in demanding applications. This sealed bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include robust construction for high rigidity, extended service life due to effective sealing, and suitability for a wide operating temperature range. The combination of a C3 radial internal clearance and ABEC 1 precision makes it a versatile and dependable choice for general industrial machinery.
6203-2RSH/C3HT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard bearing series designation, indicating a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. |
| 2RSH | The bearing is fitted with two contact seals (RSH type) on both sides. These seals provide superior protection against contaminants compared to non-contact shields. |
| C3 | Indicates a greater than normal radial internal clearance. This is beneficial for applications with thermal expansion, such as in electric motors, or where interference fits are used. |
6203-2RSH/C3HT Bearing Structural Features & Performance Benefits
- Robust Sealing for Longevity: The 2RSH contact seals effectively retain lubrication and exclude moisture, dust, and other contaminants. This results in a maintenance-free bearing with a significantly extended service life in harsh environments.
- Optimized Internal Clearance: The C3 clearance provides operational stability in applications prone to thermal expansion or where heavy interference fits are required, preventing premature failure due to excessive preload.
- High-Quality Material Construction: Manufactured from chrome steel for both rings, balls, and cage, this bearing ensures high strength, durability, and consistent performance under the specified dynamic and static load ratings.
- Broad Operating Range: With a temperature range from -30°C to 120°C, this bearing is suitable for a wide array of industrial applications without performance degradation.
