7017 CD/P4ADGC Bearing Product Overview & Core Advantages
The 7017 CD/P4ADGC is a precision angular contact ball bearing designed for demanding applications requiring high rotational accuracy and rigidity. Engineered to a P4A tolerance class, it delivers exceptional running accuracy. Its universal matchable (SU) design allows for flexible mounting in various preload configurations, while the moderate preload (Class C) ensures optimal stiffness and performance right from installation. This bearing is capable of supporting combined loads and is optimized for high-speed operation, making it an ideal choice for high-precision, high-reliability machinery.
7017 CD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Contact angle of 15° and a specific internal design for high rigidity. |
| P4A | Indicates a high-precision tolerance class with enhanced dimensional and running accuracy requirements. |
| DGC | Signifies the bearing is lubricated and supplied as part of a universally matchable (SU) set of two bearings. |
7017 CD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 15° contact angle and robust construction with a phenolic cage provide high radial and axial stiffness, enabling the bearing to handle significant combined loads.
- Precision & High-Speed Performance: Manufactured to P4A tolerance standards, this bearing ensures minimal vibration and high running accuracy. The phenolic cage contributes to a lower moment of inertia, supporting a high limiting speed of 28,000 rpm.
- Universal Matching & Simplified Assembly: The Universal Matchable (SU) designation means any two bearings can be paired in a duplex set to achieve a specific preload (in this case, moderate Class C), simplifying inventory and assembly for optimal bearing performance.
- Durability and Reliability: Constructed from chrome steel for both rings and balls, the bearing offers excellent wear resistance and a long operational life within a temperature range of -30°C to 110°C.
7017 CD/P4ADGC Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for applications requiring high speed, accuracy, and rigidity, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Aerospace Control Systems
