7011 CD/P4ADGC Bearing Product Overview & Core Advantages
The 7011 CD/P4ADGC is a precision angular contact ball bearing designed for applications requiring exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a moderate preload (Class C) duplex set, it is engineered to handle combined loads efficiently, accommodating significant radial and axial loads simultaneously. Its P4A tolerance class ensures ultra-precise running, making it ideal for high-speed spindles and other demanding machinery where high rigidity and operational reliability are paramount.
7011 CD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Indicates a duplex bearing set with a 15° contact angle arranged in a back-to-back (DB) configuration. This provides high moment rigidity. |
| P4A | Denotes an ultra-precision tolerance class, exceeding ABEC 7/ISO P4 standards, for superior running accuracy and minimal runout. |
| DGC | Signifies a universal matchable (SU) bearing pair. Two bearings can be mounted in any combination (DB, DF, DT) without preload loss, offering exceptional mounting flexibility. |
7011 CD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex (CD) design and 15° contact angle create a highly rigid system capable of withstanding substantial combined radial and axial loads. The phenolic cage contributes to stable operation under high loads.
- Precision & High-Speed Performance: Manufactured to P4A tolerance with a phenolic cage, this bearing ensures minimal vibration and is optimized for high-speed operation up to 34,000 rpm.
- Universal Matching Flexibility: The Universal Matchable (SU/DGC) feature allows for simplified installation and configuration in various duplex arrangements (back-to-back, face-to-face, or tandem) to meet specific application stiffness and load requirements.
- Durable Construction: Manufactured from chrome steel for both rings and balls, the bearing offers high fatigue life and durability in demanding environments.
7011 CD/P4ADGC Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Aerospace Control Systems
