7024 CE/P4A Bearing Product Overview & Core Advantages
The 7024 CE/P4A is a single-row angular contact ball bearing engineered for applications requiring exceptional precision and high-speed performance. Designed to accommodate combined loads (radial and axial loads in one direction), this bearing features a 15° contact angle for optimal axial load capacity. Manufactured to P4 (ABEC-7) tolerance class, it delivers superior running accuracy and rotational precision. Its phenolic cage and pre-lubrication contribute to smooth operation at limiting speeds up to 14,500 rpm, making it ideal for high-rigidity, precision spindle applications.
7024 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Advantage |
|---|---|---|
| CE | Enhanced internal design with optimized contact conditions and stabilized preload | Improved running accuracy, reduced noise/vibration, consistent performance under high speeds |
| P4A | Dimensional and running accuracy to P4 tolerance (ABEC-7 equivalent) | Superior rotational precision, minimal runout, ideal for high-precision applications |
7024 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with 15° contact angle provides excellent resistance to combined radial and axial loads. With a dynamic load rating of 12,870 lbf and static load rating of 12,375 lbf, it ensures reliable performance under demanding conditions.
- High-Speed Performance: The phenolic resin cage offers superior strength-to-weight ratio and reduced friction, enabling stable operation at limiting speeds of 14,500 rpm. The optimized internal geometry minimizes heat generation.
- Precision Engineering: Manufactured to P4 tolerance class with tight dimensional controls (bore tolerance: -0.008mm to 0), ensuring exceptional running accuracy and minimal vibration.
- Material Excellence: Chrome steel rings and balls provide high hardness, wear resistance, and extended service life under high-speed operation.
