S7024 CD/HCP4ADGA Bearing Product Overview & Core Advantages
The S7024 CD/HCP4ADGA is a high-precision double row angular contact ball bearing engineered for demanding applications requiring exceptional rigidity and speed. Its universal matchable (SU) design allows for flexible mounting in any arrangement, providing superior performance under combined radial and axial loads. Manufactured to P4A super-precision tolerance and featuring a phenolic cage with ceramic balls, this bearing is the ideal solution for high-speed, high-rigidity spindles and other precision machinery where uncompromising accuracy and reliability are paramount.
S7024 CD/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CD | 15° contact angle and universal matchable (SU) design | Optimized for combined loads; provides mounting flexibility in any arrangement (back-to-back, face-to-face, or tandem). |
| HC | Hybrid Ceramic (Silicon Nitride balls) | Enables higher limiting speeds, reduces friction and heat generation, and extends service life. |
| P4A | Super Precision Tolerance Class (ABEC 7 / ISO P4) | Guarantees extremely tight running accuracy for applications requiring minimal runout and vibration. |
| DGA | Sealed on both sides with high-performance grease | Provides effective contamination exclusion and long-term, maintenance-free lubrication. |
S7024 CD/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design and extra light preload (Class A) provide exceptional system stiffness, enabling precise control under significant combined radial and axial loads from both directions.
- Superior High-Speed Performance: The combination of a lightweight phenolic resin cage and low-friction ceramic balls (Hybrid) significantly reduces centrifugal forces and operating temperatures, allowing for a high limiting speed of 10,000 rpm.
- Precision & Longevity: Manufactured to P4A tolerance class from high-grade chrome steel, this bearing ensures minimal vibration and extended service life in the most demanding precision applications.
- Maintenance-Free Operation: The integral seals and factory-filled grease lubrication protect against contaminants and provide reliable performance across a wide temperature range from -30°C to 110°C.
S7024 CD/HCP4ADGA Bearing Typical Application Areas
This bearing is specifically designed for high-performance machinery, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, semiconductor manufacturing equipment.
- High-Speed Motors: Motors and drives requiring high rigidity and speed.
- Medical & Laboratory Equipment: Centrifuges and other precision instruments.
