S7005 CD/P4ADBB Bearing Product Overview & Core Advantages
The S7005 CD/P4ADBB is a precision duplex angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This matched back-to-back (DB) arrangement provides superior stability and can accommodate combined radial and axial loads from both directions. Manufactured to ABEC 7 / P4A tolerance class with a light preload (Class B), it ensures smooth, high-precision operation and is ideally suited for high-speed spindles and other critical machinery where maximum rigidity and running accuracy are paramount.
S7005 CD/P4ADBB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| S7005 | Precision angular contact ball bearing series with 25mm bore. |
| C | 15° contact angle. |
| D | Duplex (two bearings in a set). |
| P4A | High precision tolerance class (equivalent to ABEC 7). |
| DB | Back-to-Back arrangement for high moment rigidity. |
| B | Light preload (Class B). |
S7005 CD/P4ADBB Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) arrangement creates a wide, rigid support system that effectively resists moment loads and shaft deflection, ensuring exceptional operational stability.
- Superior Load Capacity: With a 15° contact angle, this bearing is engineered to handle significant combined radial and axial loads simultaneously, making it suitable for complex loading conditions.
- Optimized High-Speed Performance: The lightweight phenolic resin cage and precision-ground chrome steel components contribute to low friction and vibration, enabling a high limiting speed of 83,000 rpm.
- Precision & Longevity: Manufactured to P4A tolerance class with a light preload, it guarantees high running accuracy and reduced noise. The sealed design retains factory-applied grease, protecting against contamination for consistent, long-term performance.
