S7005 CD/P4ADFB Bearing Product Overview & Core Advantages
The S7005 CD/P4ADFB is a precision duplex angular contact ball bearing designed for applications requiring exceptional rotational accuracy and rigidity. This matched set features a Face-to-Face (DF) arrangement and a Light (Class B) preload, delivering superior system stability and runout control. Its primary advantage lies in its ability to handle combined radial and axial loads simultaneously, making it an ideal solution for high-precision, high-speed machinery where uncompromising performance is critical. Manufactured to P4A tolerance class, it ensures minimal vibration and exceptional operational smoothness.
S7005 CD/P4ADFB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7005 | Basic bearing series, indicating a 25mm bore diameter. |
| C | 15° contact angle. |
| D | Duplex (two bearings supplied as a matched set). |
| P4A | High precision tolerance class exceeding ABEC 7, ensuring ultra-low runout and vibration. |
| DF | Face-to-Face mounting arrangement, providing high moment stiffness. |
| B | Light preload (Class B), optimized for high-speed operation and reduced friction. |
S7005 CD/P4ADFB Bearing Structural Features & Performance Benefits
- High Rigidity & System Stability: The duplex DF arrangement and light preload create an exceptionally rigid bearing system, effectively resisting operational moments and deflection for superior positional accuracy.
- Superior Load Capacity: The 15° contact angle is optimized to handle significant combined radial and axial loads from both directions, a hallmark of angular contact design.
- High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the grease lubrication and precision construction enable a high limiting speed of 83,000 rpm, making it a true high-speed bearing.
- Precision & Longevity: Manufactured to P4A tolerance class from high-grade chrome steel, this bearing guarantees low noise, minimal heat generation, and extended service life in demanding applications.
S7005 CD/P4ADFB Bearing Typical Application Areas
