6304-2RSH/C4 Bearing Product Overview & Core Advantages
The 6304-2RSH/C4 is a single row deep groove ball bearing designed for high-performance industrial applications. Engineered with sealed construction and increased radial internal clearance (C4), this bearing excels in handling significant radial loads while accommodating moderate axial loads in both directions. Its precision ABEC 1 | ISO P0 tolerance ensures reliable operation, making it ideal for applications demanding consistent performance under varying thermal conditions and heavy-duty cycles.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6304 | Standard deep groove ball bearing series with 20mm bore, 52mm OD, 15mm width |
| 2RSH | Double rubber contact seals on both sides for superior contamination protection |
| C4 | Increased radial internal clearance for applications with thermal expansion or heavy interference fits |
6304-2RSH/C4 Bearing Structural Features & Performance Benefits
Optimized Sealing System: The 2RSH rubber contact seals provide excellent protection against contaminants while retaining lubrication effectively, extending service life in harsh environments.
Enhanced Thermal Performance: With C4 radial clearance, this bearing accommodates differential thermal expansion between shaft and housing, preventing premature failure in high-temperature applications.
Robust Load Capacity: Featuring chrome steel construction throughout (rings, balls, and cage), the bearing delivers high dynamic load capacity (3574 lbf) and reliable performance under continuous radial loads.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent dimensional accuracy and smooth operation across the entire temperature range (-30° to 120°C).
6304-2RSH/C4 Bearing Typical Application Areas
- Electric Motors and Industrial Gearboxes requiring reliable sealed bearings
- Material Handling Equipment such as conveyor systems and pulley assemblies
- Agricultural Machinery operating in dusty or contaminated environments
- Pump Systems and Compressors where thermal expansion must be accommodated
- General Industrial Machinery requiring maintenance-free operation with high radial load capacity
