6330/C4 Bearing Product Overview & Core Advantages
The 6330/C4 is a single row deep groove ball bearing engineered for demanding industrial applications requiring robust radial load capacity and reliable performance. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers excellent precision and operational stability. Its key advantage lies in the optimized C4 radial internal clearance, making it particularly suitable for applications with significant thermal expansion or where interference fits are used, ensuring consistent performance under varying operational conditions. The open design allows for versatile lubrication options tailored to specific application needs.
6330/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6330 | Standard bearing series designation indicating dimensions: 150mm bore, 320mm OD, 65mm width |
| /C4 | Radial internal clearance group larger than normal, suitable for applications with thermal expansion or interference fits |
6330/C4 Bearing Structural Features & Performance Benefits
Enhanced Load Capacity: The deep groove raceway and optimized geometry provide exceptional radial dynamic load rating of 62,047 lbf and radial static load rating of 64,071 lbf, ensuring reliable operation under heavy loads.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with precise dimensional control (bore tolerance: -0.018mm to 0), delivering consistent performance and easy installation.
Thermal Compensation: The C4 radial clearance accommodates thermal expansion in high-temperature applications or interference fits, preventing premature failure due to excessive preload.
Material Excellence: Constructed entirely from chrome steel for rings, balls, and cage, providing superior strength, wear resistance, and durability across the operating temperature range of -30°C to 120°C.
Versatile Configuration: The open seal type design allows for custom lubrication solutions, while the limiting speed of 2,800 rpm ensures reliable high-speed operation.
