6307/C3HVB007 Bearing Product Overview & Core Advantages
The 6307/C3 is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Engineered from high-grade chrome steel, this open-type bearing excels at handling primarily radial loads and offers reliable operation. A key feature is its specified C3 radial internal clearance, which makes it particularly suitable for applications involving thermal expansion, heavy loads, or where interference fits are used, ensuring optimal performance and extended service life.
6307/C3HVB007 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Significance & Advantage |
| 6307 | Standard designation for a single row deep groove ball bearing with 35mm bore, 80mm OD, and 21mm width. | Defines the fundamental bearing dimensions and type, ensuring interchangeability. |
| /C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Prevents bearing seizure in applications with high operational temperatures or tight fits, enhancing reliability. |
6307/C3HVB007 Bearing Structural Features & Performance Benefits
Optimized Deep Groove Raceway: The geometry of the raceways allows for smooth operation and efficient handling of radial loads, as well as moderate axial loads in both directions.
High-Grade Material Construction: Manufactured from chrome steel for rings, balls, and cage, this bearing provides high strength, durability, and resistance to wear.
Enhanced Operational Flexibility: The C3 clearance is a critical performance feature. It accommodates differential thermal expansion between the shaft and housing, preventing preload and potential damage, which is vital for applications with fluctuating temperatures.
Standard Precision & High-Speed Capability: Conforming to ABEC 1 | ISO P0 tolerance class, it offers consistent quality for general industrial use. The limiting speed of 8,500 rpm makes it suitable for a broad spectrum of high-speed machinery.
6307/C3HVB007 Bearing Typical Application Areas
The 6307/C3 is a versatile component found in numerous sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Compressors
