S7010 CDGC/P4A Bearing Product Overview & Core Advantages
The S7010 CDGC/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single bearing with universal matching capability (SU designation), it can be flexibly paired with identical bearings in various arrangements to achieve optimal preload and system performance. Its P4A super-precision tolerance ensures minimal runout and vibration, making it ideal for high-speed spindles and precision machinery. The phenolic cage and optimized 15° contact angle contribute to its outstanding high-speed performance and ability to handle combined loads (radial and axial) simultaneously.
S7010 CDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7010 | Basic bearing series and size designation (50mm bore, 80mm OD, 16mm width). |
| C | 15° nominal contact angle. |
| DG | Universal Matchable bearing. Two bearings can be paired in a back-to-back (DB) or face-to-face (DF) arrangement. |
| C | Moderate preload (Class C). |
| P4A | Super-precision tolerance class, exceeding ABEC 7/ISO P4 standards for enhanced running accuracy. |
S7010 CDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The optimized internal geometry and 15° contact angle provide excellent resistance to combined loads, ensuring stable operation under demanding conditions.
- Superior High-Speed Performance: The lightweight and robust phenolic resin cage minimizes centrifugal forces and friction, enabling a high limiting speed of 46,000 rpm. The standard grease lubrication is formulated for stable performance across the operating temperature range.
- Precision Engineering: Manufactured to P4A tolerance class, this bearing guarantees extremely tight dimensional and running accuracy, which is critical for applications requiring minimal vibration and high positional accuracy.
- Universal Matching (SU): This feature allows for simplified inventory and highly flexible bearing arrangement designs. Multiple S7010 CDGC/P4A bearings can be directly matched to create a preloaded set without the need for selective assembly.
