7016 CDGD/P4A Bearing Product Overview & Core Advantages
The 7016 CDGD/P4A is a precision angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. Engineered with a 15° contact angle and a Heavy preload (Class D), this bearing delivers superior performance under combined loads. Its P4A tolerance class ensures ultra-precise running accuracy, making it ideal for high-speed spindles and other precision machinery where minimal deflection and high rotational accuracy are critical.
7016 CDGD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code | Interpretation | Technical Significance |
|---|---|---|
| 7016 | Basic Bearing Series | Denotes a metric series angular contact ball bearing with an 80mm bore, 125mm OD, and 22mm width. |
| C | 15° Contact Angle | Optimized for handling high axial loads in one direction combined with radial loads. |
| DG | Universal Matchable (SU) | The bearing is universally matchable, allowing any two bearings to be paired in a duplex set without selective matching. |
| D | Heavy Preload (Class D) | Indicates a heavy preload is applied, maximizing system rigidity and minimizing axial/radial play under operational conditions. |
| P4A | Tolerance Class | Signifies an ultra-precision tolerance grade, exceeding ABEC-7 standards, for applications requiring exceptional running accuracy. |
7016 CDGD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Preload: The Heavy preload (Class D) significantly increases bearing stiffness, reducing deflection under load and enhancing the dynamic response of the entire system. This is critical for maintaining precision in machining and positioning applications.
- Superior Load Capacity: The 15° contact angle design provides excellent capability to handle combined radial and axial loads simultaneously. With a dynamic load rating of 14,625 lbf and a static load rating of 13,725 lbf, it offers robust performance in demanding conditions.
- Precision & High-Speed Operation: Manufactured to P4A tolerance class and featuring a lightweight, durable phenolic cage, this bearing supports a high limiting speed of 17,000 rpm. The precision construction ensures smooth, low-vibration, and low-noise operation at high velocities.
- Universal Matching & Simplified Assembly: The Universal Matchable (SU) designation allows for simplified inventory and assembly, as any two bearings can be mounted together in a back-to-back or face-to-face arrangement to achieve the required preload and stiffness without selective grading.
7016 CDGD/P4A Bearing Typical Application Areas
This bearing is engineered for high-performance applications where precision, speed, and rigidity are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and rotary actuators requiring high positional accuracy.
- High-Frequency Motors and Spindles: Applications in PCB drilling and semiconductor manufacturing equipment.
- Medical Equipment: High-speed centrifuges and precision surgical handpieces.
- Aerospace & Defense: Gyroscopes, radar systems, and other precision instrumentation.
