7011 CE/P4ADT Bearing Product Overview & Core Advantages
The 7011 CE/P4ADT is a duplex tandem (DT) arrangement of two precision angular contact ball bearings, designed for applications requiring exceptional axial load capacity and high rigidity. This P4A tolerance class matched set offers superior running accuracy and is preloaded for immediate, precise operation. Its compact design and high limiting speed of 39,000 rpm make it ideal for demanding, high-speed machinery where uncompromising performance and reliability are critical.
7011 CE/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| CE | Indicates a 15° contact angle, optimized for high axial load capacity and moderate radial loads. |
| P4A | Denotes a high-precision tolerance class with enhanced dimensional and running accuracy for superior performance. |
| DT | Signifies a Duplex Tandem arrangement, where two bearings are mounted to significantly increase axial load capacity in one direction. |
7011 CE/P4ADT Bearing Structural Features & Performance Benefits
- High Rigidity & Axial Load Capacity: The duplex tandem (DT) arrangement combines two bearings to create an exceptionally rigid support system, capable of handling very high unidirectional axial loads.
- Precision Performance: Manufactured to P4A tolerance class, this bearing set ensures minimal runout and vibration, which is critical for high-speed and high-precision applications.
- High-Speed Capability: The lightweight phenolic resin cage and optimized internal geometry contribute to a high limiting speed, reducing centrifugal forces and maintaining stability at 39,000 rpm.
- Preload & Immediate Accuracy: The set is supplied preloaded, eliminating internal clearance for immediate high positional accuracy and stiffness without requiring adjustment during installation.
7011 CE/P4ADT Bearing Typical Application Areas
This bearing is engineered for high-performance applications, including:
- Machine Tool Spindles (especially for grinding and milling)
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Aerospace Actuation Systems
