6306/C3S1 Bearing Product Overview & Core Advantages
The 6306/C3S1 is a single row deep groove ball bearing engineered for exceptional radial load capacity and reliable performance in demanding industrial applications. Featuring C3 radial internal clearance and ABEC 1 precision, this bearing delivers stable operation under varying thermal conditions and moderate speeds. Its open design allows for versatile lubrication options while maintaining high rigidity and dimensional stability. Manufactured from premium chrome steel throughout, it ensures consistent performance and long service life across a wide temperature range from -30°C to 200°C.
6306/C3S1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
|---|---|---|
| 6306 | Standard deep groove ball bearing series with 30mm bore diameter | Standard dimensions for universal compatibility |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, ideal for high-temperature applications |
| S1 | Stabilized heat treatment up to 200°C | Maintains dimensional stability at elevated temperatures |
6306/C3S1 Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The single row deep groove raceway geometry enables efficient handling of radial loads up to 6002 lbf dynamic capacity, while also accommodating moderate axial loads in both directions.
Thermal Performance: With C3 clearance and S1 heat stabilization, this bearing maintains operational integrity during thermal expansion, preventing binding or excessive preload in high-temperature environments.
Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance class with tight dimensional control (bore tolerance: -0.01mm to 0), ensuring smooth operation and precise shaft positioning.
Material Excellence: All-steel construction using chrome steel for rings, balls, and cage provides uniform thermal expansion characteristics and excellent wear resistance.
