S7006 ACDTP/P4B Bearing Product Overview & Core Advantages
The S7006 ACDTP/P4B is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. As a single-row bearing with a 25° contact angle and factory-applied preload, it is engineered to handle combined loads—simultaneously supporting high radial loads and substantial axial loads in one direction. Its compact design, featuring a 30 mm bore and 13 mm width, makes it ideal for space-constrained, high-speed applications such as machine tool spindles. Manufactured to the exacting P4 (ABEC-7) tolerance class, it guarantees superior running accuracy and consistent performance.
S7006 ACDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| AC | Angular Contact | Optimized for combined radial and axial loads. |
| DT | Duplex Tandem Arrangement | Two bearings are mounted in tandem to increase axial load capacity in one direction. |
| P | Preload | Eliminates internal clearance for enhanced rigidity and precise shaft positioning. |
| P4B | P4 Tolerance with Specific Running Accuracy | Guarantees extremely tight dimensional and running accuracy (superior to ABEC-7). |
S7006 ACDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a 25° contact angle and factory-set preload provides exceptional system stiffness, minimizing deflection under load and ensuring precise rotational accuracy for critical applications.
- Superior Load Capacity: Engineered to handle significant combined loads. The design efficiently supports high radial loads and high unidirectional axial loads, making it suitable for demanding operational conditions.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the high-grade chrome steel construction ensures dimensional stability, enabling reliable operation at the high limiting speed of 28,000 rpm.
- Pre-Lubricated and Sealed: The bearing comes lubricated and sealed, protecting against contamination and retaining lubricant. This contributes to long service life and reduces maintenance requirements.
S7006 ACDTP/P4B Bearing Typical Application Areas
This bearing is ideally suited 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 Grinding Spindles: Applications requiring ultra-fine surface finishes.
- High-Frequency Motors and Spindles: Where minimal runout and high rotational accuracy are critical.
- Industrial Pumps and Compressors: For robust performance under combined loads.
