7007 CE/P4ADBB Bearing Product Overview & Core Advantages
The 7007 CE/P4ADBB is a precision duplex angular contact ball bearing designed for applications requiring exceptional rotational accuracy and rigidity. This matched back-to-back arrangement (DB) provides superior stability when handling combined radial and axial loads from both directions. Manufactured to P4A tolerance class and featuring a light preload (Class B), it delivers high running accuracy, reduced vibration, and is ideally suited for high-speed spindles and other precision machinery demanding maximum performance and reliability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7007 | Basic bearing series, indicating a 35 mm bore, 62 mm OD, and 28 mm width. |
| CE | Internal design featuring a 15° contact angle and optimized internal geometry. |
| P4A | High precision tolerance class exceeding ABEC 7 standards, ensuring minimal runout and vibration. |
| DB | Duplex Back-to-Back mounting arrangement. Two bearings are supplied as a matched set for high rigidity and moment load capacity. |
7007 CE/P4ADBB Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The back-to-back duplex arrangement (DB) creates a wide effective spread of load points, significantly increasing system rigidity and resistance to moment loads, which is critical for maintaining precision under operating forces.
- Superior Load Capacity: The angular contact design with a 15° contact angle enables the bearing to efficiently support substantial combined radial and axial loads simultaneously.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the precision-ground chrome steel components and optimized internal geometry contribute to a high limiting speed of 56,000 rpm.
- Precision & Accuracy: Manufactured to P4A tolerance class with a light preload, this bearing ensures minimal runout, smooth operation, and extended service life in demanding applications.
7007 CE/P4ADBB Bearing Typical Application Areas
