6004-2RSH/C3HT Bearing Product Overview & Core Advantages
The 6004-2RSH/C3 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing features integral contact seals (2RSH) for effective contamination exclusion and is supplied with a greater radial internal clearance (C3) to accommodate thermal expansion in applications with significant temperature fluctuations. Its robust construction from chrome steel ensures durability and a long service life, making it an excellent choice for applications requiring consistent operation under radial loads.
6004-2RSH/C3HT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6004 | Standard bearing series designation (20mm bore, 42mm OD, 12mm width) | Standardized dimensions for easy interchangeability. |
| 2RSH | Bearing with two (2) contact seals (RS) made of NBR rubber with steel reinforcement (H) | Superior sealing effectiveness against dust and moisture compared to non-contact shields. |
| C3 | Greater radial internal clearance than the Normal (CN) group. | Prevents preload and binding in applications with high operating temperatures or where fits result in clearance reduction. |
6004-2RSH/C3HT Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Quality Steel: The optimized raceway geometry and use of chrome steel for rings and balls provide high radial load capacity and smooth, low-vibration operation.
- Sealed for Protection & Long Life: The 2RSH contact seals effectively retain the factory-applied grease and exclude contaminants, enhancing reliability and reducing maintenance needs. The bearing is supplied unlubricated, allowing for application-specific grease selection.
- Accommodates Thermal Expansion: The C3 clearance is a critical feature for applications where shaft and housing materials have different coefficients of thermal expansion, or where operational heat is generated, preventing premature failure due to excessive preload.
- Standardized Precision: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing offers a cost-effective balance of precision and performance for a wide range of industrial uses.
6004-2RSH/C3HT Bearing Typical Application Areas
This versatile bearing is ideally suited for:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Agricultural Machinery
- Material Handling Equipment (e.g., conveyor pulleys)
- Automotive Components (e.g., alternators, idlers)
- General Industrial Machinery requiring robust, sealed ball bearing solutions.
