S7006 CE/HCP4ADBA Bearing Product Overview & Core Advantages
The S7006 CE/HCP4ADBA is a precision duplex pair of angular contact ball bearings designed for the most demanding applications. This matched set in a Back-to-Back (DB) arrangement delivers exceptional high rigidity and stability, making it ideal for spindles requiring high running accuracy. Its core advantages include the ability to support combined loads (radial and axial), superior high-speed performance enabled by a phenolic cage and ceramic balls, and long-term reliability with its sealed and pre-lubricated design.

| S7006 | Basic bearing series and size designation (30mm bore, 55mm OD). |
| C | 15° contact angle. |
| E | Optimized internal design. |
| HC | Hybrid Ceramic: Ceramic balls with steel rings. |
| P4A | High precision tolerance class (equivalent to ABEC 7). |
| DB | Duplex Back-to-Back matched arrangement. |
| A | Extra light preload. |
S7006 CE/HCP4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex pair in a Back-to-Back (DB) arrangement creates a rigid bearing system that effectively resists overturning moments, ensuring exceptional operational stability for spindles.
- Superior High-Speed Capability: The combination of ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic cage significantly lowers friction and temperature rise, enabling a high limiting speed of 100,500 rpm.
- Enhanced Load Capacity: The 15° contact angle and robust construction provide reliable performance under combined radial and axial loads.
- Long Service Life & Reduced Maintenance: The sealed design and factory-applied grease lubrication protect against contamination and provide long-term, maintenance-free operation within the specified temperature range.
- Precision Performance: Manufactured to a P4A tolerance class, this bearing guarantees high running accuracy and minimal vibration, which is critical for precision machining and equipment.
S7006 CE/HCP4ADBA Bearing Typical Application Areas
This bearing is engineered for high-performance machinery where precision, speed, and rigidity are paramount. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving, and high-frequency motor spindles.
- Robotics: High-accuracy rotary joints and arm actuators.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and other critical rotating assemblies.
