S7024 ACD/HCP4ADGB Bearing Product Overview & Core Advantages
The S7024 ACD/HCP4ADGB is a precision double row angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and reliability. Its design excels at simultaneously handling combined loads, including significant radial and bidirectional axial loads. Featuring a light preload (Class B) and manufactured to P4A super-precision tolerance, this bearing delivers superior running accuracy, high rigidity, and smooth operation. The combination of a ceramic ball material and a phenolic cage contributes to its outstanding high-speed performance and extended service life.
S7024 ACD/HCP4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Indicates a specific internal design and contact angle (25°) optimized for angular contact applications. |
| HC | Refers to the Hybrid Ceramic construction, utilizing ceramic balls for reduced friction and higher speed capability. |
| P4A | Denotes a super-precision tolerance class, ensuring extremely tight dimensional and running accuracy. |
| DGB | Signifies a Universal Matchable (SU) bearing, designed to be paired with another identical bearing in a pre-configured set (2 bearings) to achieve specific stiffness and performance characteristics. |
S7024 ACD/HCP4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling stable performance under combined loads. With a high dynamic load rating of 40050 lbf, it is built for longevity in strenuous conditions.
- Superior High-Speed Performance: The lightweight phenolic resin cage and low-friction ceramic balls (Si3N4) significantly reduce centrifugal forces and operating temperatures, allowing for a high limiting speed of 10,000 rpm.
- Precision & Accuracy: Manufactured to P4A tolerance class with extremely tight bore and outside diameter tolerances, this bearing guarantees minimal runout and vibration for ultra-precise applications.
- Sealed & Pre-Lubricated: The sealed design with pre-applied grease protects against contamination and provides reliable lubrication within the specified temperature range of -30°C to 110°C, offering a maintenance-free solution.
