S7006 CE/P4ADBA Bearing Product Overview & Core Advantages
The S7006 CE/P4ADBA is a precision duplex pair of double row angular contact ball bearings, pre-configured in a Back-to-Back (DB) arrangement. This matched set is engineered for applications demanding high rigidity and exceptional running accuracy, as defined by the P4A tolerance class. Its design is optimized to handle combined loads—significant radial loads and bidirectional axial loads—simultaneously, making it an ideal, compact solution for high-performance spindles and precision machinery where reliability is paramount.
S7006 CE/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Benefit |
|---|---|---|
| S7006 | Basic bearing series and size designation. | Defines the core bearing dimensions (30mm bore, 55mm OD, 26mm width). |
| C | 15° contact angle design. | Optimized for axial load capacity while maintaining good radial load performance. |
| E | Reinforced structure. | Increased load capacity and high rigidity. |
| P4A | High precision tolerance class. | Guarantees extremely tight dimensional and running accuracy for superior performance in precision applications. |
| DB | Duplex Back-to-Back arrangement. | Provides high moment rigidity and stable preload, ideal for withstanding complex combined loads. |
| A | Extra light preload. | Minimizes friction and heat generation, contributing to the high limiting speed of 100,500 rpm. |
S7006 CE/P4ADBA Bearing Structural Features & Performance Benefits
- Duplex Back-to-Back (DB) Design: This pre-matched pair creates a highly rigid bearing system that can withstand moment loads and complex combined loads effectively, ensuring precise shaft positioning and minimal deflection.
- High Rigidity & Load Capacity: The double row angular contact design, combined with the reinforced structure (suffix E) and phenolic cage, provides exceptional high rigidity and a dynamic load rating of 3398 lbf, enabling stable operation under demanding conditions.
- Superior High-Speed Performance: The lightweight phenolic cage, 15° contact angle, and extra light preload (A) work in concert to reduce centrifugal forces and friction, allowing for the exceptionally high limiting speed.
- Pre-Configured Precision: As a factory-matched set with P4A tolerances, this bearing pair guarantees optimal performance without the need for selective mounting, saving time and ensuring consistent, high-accuracy operation.
S7006 CE/P4ADBA Bearing Typical Application Areas
This bearing is specifically designed for high-end, precision-driven applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles
- High-Frequency Motors
- Medical and Dental Equipment Spindles
- Advanced Robotics: Precision joints and arm linkages.
