6304/C2 Bearing Product Overview & Core Advantages
The 6304/C2 is a single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Engineered with open construction and manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing delivers exceptional rotational accuracy. Its C2 radial internal clearance makes it particularly suitable for applications with precise fit requirements and controlled thermal expansion. The bearing's optimized geometry provides excellent radial load capacity while maintaining capability for moderate axial loads in both directions.
6304/C2 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
|---|---|---|
| 63 | Medium series deep groove ball bearing | Balanced size-to-capacity ratio |
| 04 | Bore diameter: 20 mm | Standard shaft size compatibility |
| C2 | Radial internal clearance smaller than normal | Reduced noise and vibration; ideal for precision applications |
6304/C2 Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured from chrome steel for both rings and balls, ensuring consistent hardness and wear resistance. The single row deep groove design provides optimal stress distribution across the bearing raceways.
Enhanced Load Capacity: With a dynamic load rating of 3574 lbf and static load rating of 1765 lbf, this bearing delivers reliable performance under substantial radial loads while accommodating combined loads effectively.
High-Speed Capability: The limiting speed of 14,000 rpm makes it suitable for high-rotation applications. The optimized cage design and precise ball guidance ensure stable operation at elevated speeds.
Tight Dimensional Control: Featuring bore diameter tolerance of -0.01mm to 0 and outside diameter tolerance of -0.013mm to 0, enabling precise fits and reduced runout in critical applications.
