7011 CE/P4ADGC Bearing Product Overview & Core Advantages
The 7011 CE/P4ADGC is a premium double row angular contact ball bearing engineered for applications demanding exceptional precision and reliability. This precision bearing is designed to accommodate combined loads—simultaneous radial and bidirectional axial loads—with high efficiency. Its compact design, featuring two rows of balls and a 15° contact angle, provides superior high rigidity and rotational accuracy. Manufactured to the exacting P4A tolerance class, it is ideally suited for high-speed spindles and other precision machinery requiring outstanding running accuracy and dimensional stability.
7011 CE/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates a universal matchable bearing designed for flexible mounting arrangements (typically used in pairs). |
| P4A | Denotes a high precision tolerance class with enhanced running accuracy requirements for the inner and outer rings. |
| DGC | Signifies a Moderate / Class C preload applied to the bearing, optimizing rigidity and minimizing axial play for precise operation. |
7011 CE/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and optimized internal geometry provide superior high rigidity, enabling the bearing to handle significant combined loads effectively.
- Precision & High-Speed Performance: Manufactured to P4A tolerances and featuring a lightweight phenolic cage, this bearing ensures smooth operation and is capable of achieving a limiting speed of 39,000 rpm.
- Universal Matchability (SU): The CE suffix indicates the bearing is universally matchable. Two bearings can be paired in various arrangements (back-to-back, face-to-face, or tandem) to suit specific application needs for load distribution and stiffness.
- Optimized Preload: The factory-applied Moderate (C class) preload ensures immediate high running accuracy and stiffness upon installation, reducing setup complexity.
- Material Quality: Constructed from high-grade chrome steel for both rings and balls, ensuring durability, long service life, and consistent performance under demanding conditions.
7011 CE/P4ADGC Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Grinding Spindles
- High-Frequency Motors
- Industrial Pumps and Compressors
- Robotic Arm Joints and Precision Gearboxes
