S7009 CD/P4ADGA Bearing Product Overview & Core Advantages
The S7009 CD/P4ADGA is a precision double row angular contact ball bearing engineered for high-performance applications requiring exceptional rigidity and running accuracy. Designed with an extra light preload (Class A) and P4A tolerance class, this bearing delivers superior rotational precision and stability. Its double row design enables it to support combined loads—significant radial loads alongside bidirectional axial loads—simultaneously. The combination of a phenolic cage and factory-applied grease makes it an ideal high-speed bearing solution for compact, high-reliability installations where minimal maintenance is desired.
S7009 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| CD | Universal Matchable bearing arrangement in a duplex pair | Provides optimized axial rigidity and moment load capacity when mounted with a second, identical bearing. |
| P4A | High precision tolerance class exceeding ABEC 7 | Ensures extremely low running noise and vibration for smooth, precise operation. |
| DGA | Contact angle of 15° with specific internal design | Optimized for high-speed operation while maintaining excellent axial load carrying capacity. |
S7009 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design and universal matchable (SU) configuration provide exceptional stiffness, enabling the bearing to handle combined radial and bidirectional axial loads effectively. This makes it suitable for applications with complex loading conditions.
- Superior High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the 15° contact angle and optimized internal geometry contribute to a high limiting speed of 46,000 rpm. The factory-applied grease lubrication is formulated for stable performance across the operating temperature range.
- Precision & Longevity: Manufactured to P4A tolerance class with tight bore and outside diameter tolerances, this bearing ensures minimal runout and consistent performance. The sealed design and pre-greasing offer a long service life with minimal maintenance requirements.
S7009 CD/P4ADGA Bearing Typical Application Areas
The S7009 CD/P4ADGA is ideally suited for high-precision, high-speed machinery where reliability and accuracy are paramount. Key application areas include:
- Machine Tool Spindles: For CNC milling, grinding, and turning centers requiring high rigidity and running accuracy.
- High-Frequency Spindles: In PCB drilling and precision engraving machines.
- Precision Instruments: Including optical scanners and coordinate measuring machines.
- Industrial Pumps & Compressors: Where reliable performance under combined loads is essential.
