7011 CE/P4A Bearing Product Overview & Core Advantages
The 7011 CE/P4A is a single-row angular contact ball bearing designed for applications requiring high precision and high-speed operation. Engineered to accommodate combined loads, it efficiently supports both radial loads and substantial axial loads in one direction. Its P4 (ABEC-7) tolerance class ensures exceptional running accuracy, making it ideal for high-reliability machinery. The bearing is pre-lubricated and features a phenolic cage, contributing to its excellent performance in demanding environments.
7011 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| CE | Indicates a 15° contact angle and that the bearing is supplied as a matched set for preload applications. |
| P4A | Denotes a high-precision tolerance class equivalent to ABEC-7, with specific running accuracy requirements. |
7011 CE/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4 tolerance standards, this bearing provides superior running accuracy and system rigidity, essential for precise positioning and minimal runout.
- Optimized Load Capacity: The 15° contact angle is engineered to handle significant combined radial and axial loads simultaneously, offering robust performance.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, enabling a high limiting speed of 34,000 rpm. This makes it suitable for high-speed spindles and other rapid-rotation applications.
- Preload & Matched Set: The CE designation signifies the bearing is supplied ready for preload arrangements, enhancing system stiffness and rotational accuracy.
- Wide Temperature Range: With an operating temperature range from -30°C to 110°C, it performs reliably in various environmental conditions.
7011 CE/P4A Bearing Typical Application Areas
This high-precision angular contact bearing is ideally suited for:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- High-Speed Pumps and Compressors
- Aerospace Control Systems
- Medical and Dental Equipment
