6203-2RSH/C2ELHT23 Bearing Product Overview & Core Advantages
The 6203-2RSH/C2ELHT23 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing features a robust construction that delivers high performance under radial loads. Its compact design, combined with precision manufacturing to ABEC 1 standards, makes it an ideal choice for applications requiring consistent operation and long service life. The bearing is pre-lubricated and sealed for life, offering a maintenance-free solution.
6203-2RSH/C2ELHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2RSH | Contact seals on both sides, Nitrile Rubber (NBR) | Provides superior contamination exclusion and effective grease retention compared to standard seals. |
| /C2 | Radial internal clearance smaller than normal (C2 group) | Reduces noise and vibration, suitable for applications with precise fits and minimal thermal expansion. |
| ELHT23 | High-temperature, synthetic hydrocarbon grease | Enables reliable operation across the specified temperature range (-30°C to 120°C) and contributes to the limiting speed of 17,000 rpm. |
6203-2RSH/C2ELHT23 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway geometry is engineered to support significant radial dynamic load ratings (2147 lbf) and radial static load ratings (1079 lbf), ensuring stable performance under load.
- Sealed for Life & Maintenance-Free: The 2RSH contact seals effectively shield the bearing internals from contaminants like dust and moisture, while retaining the high-performance ELHT23 grease. This eliminates the need for re-lubrication, reducing lifecycle costs.
- Precision & Quiet Operation: Manufactured to ABEC 1 | ISO P0 tolerance class with a C2 radial internal clearance, this bearing offers running accuracy and low noise, which is critical for sensitive applications.
- Robust Material Construction: All critical components—rings, balls, and cage—are made from chrome steel, providing high hardness, wear resistance, and a long operational lifespan.
6203-2RSH/C2ELHT23 Bearing Typical Application Areas
