S7007 CB/P4ADBB Bearing Product Overview & Core Advantages
The S7007 CB/P4ADBB is a precision duplex angular contact ball bearing designed for applications requiring exceptional rotational accuracy and rigidity. This matched back-to-back (DB) arrangement is preloaded to Light / Class B standards, providing high system stiffness and excellent running accuracy. Its primary advantage lies in its ability to support combined loads (radial and axial) simultaneously from both directions, making it ideal for high-precision, high-speed spindles and other demanding machinery.
S7007 CB/P4ADBB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7007 | Basic bearing series, 35mm bore, 62mm OD, 28mm width |
| CB | Specific internal clearance and preload designation (Light / Class B) |
| P4A | High-precision tolerance class (superior to ABEC 7) |
| DBB | Duplex arrangement: Back-to-Back (DB) mounting |
S7007 CB/P4ADBB Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The duplex back-to-back configuration and Class B preload create a highly rigid bearing system that minimizes deflection under load, ensuring exceptional positional accuracy and stability.
- Superior Load Capacity: The 15° contact angle and optimized internal geometry enable efficient handling of combined radial and thrust loads from both directions.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the grease lubrication and precision construction contribute to a high limiting speed of 41,000 rpm.
- Sealed & Ready-to-Use: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is ready for immediate installation, offering long-term, maintenance-free operation within its specified temperature range.
S7007 CB/P4ADBB Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles (milling, grinding, boring)
- High-Frequency Spindle Motors
- Precision Robotic Drives and Gearboxes
- Medical and Dental High-Speed Handpieces
- Advanced Aerospace Instrumentation and Control Systems
