7026 CD/HCP4ADGA Bearing Product Overview & Core Advantages
The 7026 CD/HCP4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. Engineered as a universally matchable (SU) pair, this bearing excels at simultaneously handling combined radial and axial loads. Its P4A super-precision tolerance and ceramic ball construction deliver superior running accuracy, high rigidity, and extended service life, making it ideal for high-speed, high-reliability machinery.
7026 CD/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Universal Matchable (SU) bearing set with a 15° contact angle. The two bearings are specially manufactured to be mounted in either a DB (back-to-back) or DF (face-to-face) arrangement. |
| HC | Hybrid Ceramic construction, indicating the use of ceramic balls with steel rings. |
| P4A | Denotes a super-precision tolerance class, exceeding ABEC 7/ISO P4 standards, for extremely low runout and vibration. |
| ADGA | Specifies an Extra light (A) preload and lubrication. The bearing is pre-lubricated for immediate operation. |
7026 CD/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The universal matchable (SU) pair design provides superior system rigidity and can accommodate combined loads and moment loads effectively. The 15° contact angle is optimized for high axial load capacity.
- High-Speed Performance: The combination of a lightweight phenolic cage, hybrid ceramic balls (lower density, reduced centrifugal force), and optimized internal geometry enables a high limiting speed of 11,000 rpm.
- Extended Service Life & Reliability: Ceramic balls are harder, lighter, and more resistant to wear and electrical arcing than steel, significantly increasing bearing life. The P4A precision ensures smooth, low-vibration operation.
- Thermal Stability: The phenolic cage and hybrid construction contribute to stable performance across the operating temperature range of -30°C to 110°C.
7026 CD/HCP4ADGA Bearing Typical Application Areas
This high-performance bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- High-Frequency Motors & Spindles: Where low vibration and high-speed capability are critical.
- Aerospace & Defense Systems: Gyroscopes, radar platforms, and other precision mechanisms.
- Medical Equipment: High-speed dental handpieces and imaging scanner gantries.
