6203-2RSH/C3HTVT200 Bearing Product Overview & Core Advantages
The 6203-2RSH/C3 is a sealed single row deep groove ball bearing engineered for reliable performance in demanding applications. Its primary advantage lies in its ability to accommodate significant radial loads while offering robust protection against contamination. The combination of high-quality rubber seals (2RS) and an optimized internal C3 clearance makes it an excellent choice for applications requiring operational stability under varying thermal conditions and moderate speeds.
Model Code Breakdown
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6203 | Standard bearing series with 17mm bore, 40mm OD, 12mm width. | Standardized dimensions for easy interchangeability and sourcing. |
| 2RS | Contact rubber seals on both sides. | Provides effective protection against contaminants like dust and moisture, retaining lubrication. |
| H | Enhanced ring and ball geometry/heat stabilization. | Improved dimensional stability under operational heat, contributing to consistent performance. |
| /C3 | Radial internal clearance greater than Normal (CN). | Accommodates thermal expansion in applications with rising temperatures, preventing preload and seizure. |
6203-2RSH/C3HTVT200 Bearing Structural Features & Performance Benefits
- Robust Sealing for Contaminant Exclusion: The double rubber contact seals (2RS) create an effective barrier, making the bearing suitable for environments with dust or humidity, thereby extending service life.
- Optimized Internal Clearance for Thermal Management: The C3 radial internal clearance is a critical feature that allows for shaft and housing expansion under operational heat, ensuring smooth running and preventing binding.
- High-Grade Material Construction: Manufactured from chrome steel for both rings and balls, the bearing provides high load capacity and durability. The standard ABEC 1 (ISO P0) tolerance ensures reliable and consistent performance for a wide range of industrial applications.
- High-Speed Capability: With a limiting speed of 17,000 rpm, it is well-suited for a variety of motor and drive applications requiring moderate to high rotational velocities.
6203-2RSH/C3HTVT200 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors: Ideal for main shafts in small to medium-sized AC/DC motors.
- Industrial Gearboxes and Transmissions: Provides reliable support for shafts under radial loads.
- Agricultural Machinery: Used in equipment such as pumps and conveyors where contamination resistance is crucial.
- Material Handling Equipment: Found in rollers, fans, and blowers.
- General Industrial Machinery: A standard choice for various machinery requiring a cost-effective and durable sealed bearing solution.
