7017 ACD/P4ADGC Bearing Product Overview & Core Advantages
The 7017 ACD/P4ADGC is a precision double-row angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. Its universal matchable (SU) design allows for flexible mounting arrangements, while the P4A tolerance class ensures superior dimensional and running accuracy. This bearing excels at simultaneously handling combined radial and axial loads, making it an ideal solution for high-precision, high-reliability machinery where space constraints and performance are critical.
7017 ACD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Designates a 25° contact angle and specific internal geometry optimized for high axial load capacity and rigidity. |
| P4A | Indicates an ultra-precision tolerance class with enhanced running accuracy requirements, surpassing standard P4 levels. |
| DGC | Signifies a phenolic resin cage and that the bearing is pre-lubricated from the factory. |
7017 ACD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row design and 25° contact angle provide superior stiffness, enabling the bearing to effectively support significant combined radial and axial loads from both directions.
- Precision Performance: Manufactured to P4A tolerance class, this bearing guarantees minimal runout and vibration, which is critical for maintaining high positional accuracy in demanding applications.
- Optimized High-Speed Operation: The lightweight phenolic cage (DGC) reduces centrifugal forces, contributing to stable operation at the high limiting speed of 17,000 rpm. The phenolic material also offers excellent performance under lubrication.
- Universal Matching Capability (SU): This feature allows for simplified mounting of bearings in pairs (back-to-back or face-to-face) without selective matching, reducing assembly time and complexity while ensuring optimal preload and performance.
7017 ACD/P4ADGC Bearing Typical Application Areas
This bearing is specifically designed for high-performance machinery, including:
- Machine Tool Spindles for milling, grinding, and turning centers
- Precision High-Speed Spindles in PCB drilling and routing equipment
- Rotary tables and indexing heads
- High-performance pumps and compressors
- Advanced robotics and automation systems
