6004-2RSH/C3W64F Bearing Product Overview & Core Advantages
The 6004-2RSH/C3W64F is a sealed single row deep groove ball bearing engineered for exceptional reliability and performance in demanding applications. Its core advantages stem from its robust construction and specialized features, including integral seals (2RSH) for superior contamination protection and Solid Oil lubrication (W64F) for extended service life and minimal maintenance. This bearing is designed to handle significant radial loads and moderate axial loads in both directions, making it a versatile and durable solution for a wide range of industrial machinery. The C3 radial internal clearance ensures optimal performance in applications with thermal expansion or heavy loads.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6004 | Standard bearing series designation, indicating a metric single row deep groove ball bearing with a 20mm bore, 42mm OD, and 12mm width. |
| 2RSH | Contact seals on both sides. The "RSH" suffix denotes high-performance nitrile rubber (NBR) seals with steel reinforcements, offering excellent sealing effectiveness against contaminants and moisture. |
| C3 | Radial internal clearance greater than normal (C0). This is optimal for applications where thermal expansion or heavy loads are expected, preventing preload and ensuring smooth operation. |
| W64F | Lubricated with Solid Oil. This is a polymer matrix saturated with oil, which provides a consistent lubricating film, resists wash-out, and is ideal for high-temperature or contaminated environments, significantly extending relubrication intervals. |
6004-2RSH/C3W64F Bearing Structural Features & Performance Benefits
- Superior Sealing & Contamination Resistance: The 2RSH contact seals provide a highly effective barrier against dust, dirt, and moisture. This results in a longer bearing service life and reduced risk of premature failure in harsh operating conditions, making it a maintenance-friendly component.
- Advanced Lubrication for Longevity: The Solid Oil (W64F) filling eliminates the risk of oil leakage and is not susceptible to being washed out by water or solvents. It operates reliably across the specified temperature range (-30°C to 120°C), reducing friction and wear for consistent performance.
- Optimized Internal Clearance: The C3 clearance is a critical feature for applications involving high rotational speeds or where frictional heat generation causes thermal expansion of the inner ring. It prevents binding and ensures smooth, low-vibration operation.
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 2113 lbf and a static load rating of 1135 lbf, providing reliable support for substantial radial loads.
6004-2RSH/C3W64F Bearing Typical Application Areas
The 6004-2RSH/C3W64F is ideally suited for applications requiring sealed, pre-lubricated, and robust bearings. Key industries and equipment include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor rollers, pulleys)
- Agricultural Machinery
- Food and Beverage Processing Equipment (where wash-downs are common)
- Pumps and Compressors
- Automotive Auxiliary Units (e.g., alternators, idlers)
