S7000 CD/P4ADGA Bearing Product Overview & Core Advantages
The S7000 CD/P4ADGA is a metric, double-row angular contact ball bearing designed for high-precision and high-rigidity applications. Engineered to accommodate combined loads (radial and bidirectional axial loads) simultaneously, its compact design is ideal for space-constrained installations requiring exceptional accuracy and reliability. Manufactured to the stringent P4A tolerance class and featuring a universal matchable (SU) designation, this bearing ensures superior running accuracy and simplified mounting in preloaded arrangements.
S7000 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| S7000 CD | Basic bearing series designation. | Denotes a double-row angular contact ball bearing with a 15° contact angle. |
| P4A | Tolerance Class | Indicates high-precision dimensional and running accuracy, superior to ABEC 7 (P4) standards. |
| DGA | Preload / Internal Clearance | Specifies an extra light preload (Class A), optimizing the bearing for high-speed operation with minimal friction and heat generation. |
S7000 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row design provides superior radial and axial rigidity, enabling stable performance under combined loads. It is preloaded for immediate precision operation.
- High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, contributing to a high limiting speed of 185,000 rpm. The 15° contact angle is optimized for high-speed applications.
- Precision & Durability: Manufactured from chrome steel for both rings and balls, and built to P4A tolerance, this bearing guarantees exceptional dimensional stability and long service life.
- Universal Matchability (SU): Bearings are universally matchable, allowing any two bearings to be mounted together in a back-to-back or face-to-face arrangement without pre-selection, simplifying assembly and ensuring optimal preload.
- Sealed & Lubricated for Life: The sealed construction with factory-applied grease protects against contamination and provides reliable lubrication within the specified temperature range of -30°C to 110°C, making it suitable for maintenance-free applications.
