S7010 CB/HCP4ADGA Bearing Product Overview & Core Advantages
The S7010 CB/HCP4ADGA is a super-precision double row angular contact ball bearing engineered for the most demanding applications. Its P4A tolerance class and ceramic ball construction deliver exceptional rotational accuracy and dimensional stability. This bearing is distinguished by its ability to support combined loads (radial and bidirectional axial loads) simultaneously, making it ideal for high-speed spindles and other precision machinery requiring high rigidity and minimal runout. The phenolic cage and pre-loaded universal matchable (SU) design ensure smooth, quiet operation at extreme rotational speeds.
S7010 CB/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CB | Specific internal clearance and preload (Extra light / Class A) | Optimized for high-speed operation with minimal friction and heat generation. |
| HC | Hybrid Ceramic (Silicon Nitride balls) | Reduced weight, lower centrifugal forces, and extended service life at high speeds. |
| P4A | Tolerance class superior to ABEC 7 / ISO P4 | Guarantees ultra-high precision and running accuracy for critical applications. |
| DGA | Sealed on both sides with high-performance grease | Provides effective contamination exclusion and long-term, maintenance-free lubrication. |
S7010 CB/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design and 15° contact angle provide superior resistance to moment loads and high radial dynamic load rating (3578 lbf), ensuring stable performance under combined loads.
- Exceptional High-Speed Performance: The combination of lightweight phenolic resin cage and low-density ceramic balls significantly reduces centrifugal forces, enabling a high limiting speed of 46,000 rpm.
- Precision & Longevity: Manufactured to P4A super-precision standards with a universal matchable (SU) design, this bearing offers unmatched running accuracy. The sealed construction with pre-applied grease lubrication ensures consistent performance and a long, maintenance-free service life within a temperature range of -30°C to 110°C.
S7010 CB/HCP4ADGA Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications where precision, speed, and reliability are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- Aerospace & Defense: Gyroscopes, navigation systems, and auxiliary power units.
