S7024 CD/P4ADGB Bearing Product Overview & Core Advantages
The S7024 CD/P4ADGB is a precision double-row angular contact ball bearing designed for applications demanding high rigidity and exceptional running accuracy. Engineered to a P4A tolerance class, it is ideally suited for high-speed spindles and other precision machinery. Its core advantage lies in its ability to simultaneously support substantial combined loads—both radial and bidirectional axial loads—within a compact cross-section. The combination of a light preload (Class B) and universal matchable (SU) design ensures consistent, high-performance operation with minimal heat generation and vibration.
S7024 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7024 | Basic bearing designation, indicating a double-row angular contact ball bearing with a 120mm bore, 180mm OD, and 56mm width. |
| C | 15° contact angle. |
| D | The bearing is universal matchable (SU). Two bearings can be arranged in any configuration (back-to-back, face-to-face, or tandem) to achieve the required stiffness. |
| P4A | Indicates a high-precision tolerance class, with enhanced running accuracy for spindle applications. |
| DB | Specifies that the bearing is sealed and pre-lubricated with grease, offering protection from contamination and enabling long-term, maintenance-free operation. |
S7024 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row design and optimized internal geometry provide superior rigidity, enabling the bearing to handle significant combined loads effectively. The light preload eliminates internal clearance, enhancing system stiffness and rotational accuracy.
- Precision & High-Speed Performance: Manufactured to P4A tolerances, this bearing ensures minimal runout and vibration. The phenolic cage is lightweight and robust, contributing to smooth operation at high rotational speeds, with a limiting speed of 10,000 rpm.
- Versatile Mounting & Long Service Life: The universal matchable (SU) feature provides exceptional flexibility in mounting arrangements. The integral seals and factory-applied grease lubrication protect against contaminants and sustain performance across a wide temperature range from -30°C to 110°C, ensuring reliability and reducing maintenance needs.
