6304-2RSH/C3 Bearing Product Overview & Core Advantages
The 6304-2RSH/C3 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This sealed bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include robust construction with chrome steel components, extended service life due to integrated seals, and a C3 radial internal clearance suitable for applications with thermal expansion or heavy interference fits. Engineered to ABEC 1 | ISO P0 tolerance standards, it delivers consistent precision and high reliability for industrial machinery.
6304-2RSH/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6304 | Basic bearing series designation, indicating a medium-duty deep groove ball bearing with 20mm bore, 52mm OD, and 15mm width. |
| 2RSH | Double-sided contact seals made of NBR rubber with steel reinforcements. The "H" indicates high-temperature resistant seals, offering superior contamination protection and grease retention. |
| C3 | Radial internal clearance greater than normal (C0). This clearance is ideal for applications with expected thermal expansion, heavy press fits, or where reduced friction is desired. |
6304-2RSH/C3 Bearing Structural Features & Performance Benefits
- Optimized Sealing System: The 2RSH contact seals provide excellent protection against contaminants and moisture while effectively retaining lubrication. This results in extended service intervals and reliable operation in harsh environments.
- Robust Load Capacity: Manufactured from high-grade chrome steel (GCr15) for both rings and balls, the bearing delivers a dynamic load rating of 3574 lbf and a static load rating of 1765 lbf, ensuring durability under significant radial stresses.
- Precision & Stability: Built to ABEC 1 (ISO P0) precision class, it guarantees consistent running accuracy and low vibration, contributing to smoother machine operation.
- Thermal & Speed Performance: The C3 clearance accommodates thermal expansion, preventing seizure at high temperatures. With a limiting speed of 14,000 rpm, it is suitable for a wide range of high-speed applications.
