S7016 CDGA/HCP4A Bearing Product Overview & Core Advantages
The S7016 CDGA/HCP4A is a high-precision angular contact ball bearing engineered for applications demanding exceptional rotational accuracy, high-speed capability, and superior rigidity. As a single bearing with a 15° contact angle and P4A super-precision tolerance, it is designed to handle combined loads—significant radial loads alongside axial loads in one direction. Its construction with ceramic balls and a phenolic cage contributes to lower friction, higher limiting speeds, and extended service life, making it an ideal choice for high-performance spindles and precision machinery.
S7016 CDGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7016 | Basic bearing series and size designation (80mm bore, 125mm OD, 22mm width). |
| C | 15° nominal contact angle. |
| DG | Universal Matchable bearing. Can be mounted in tandem, back-to-back, or face-to-face arrangements with other universal match bearings to form a matched set. |
| A | Extra light preload class. Provides minimal internal clearance for high rigidity and precise shaft positioning. |
| HC | Hybrid Ceramic. Signifies the use of ceramic balls (typically Silicon Nitride) with steel rings. |
| P4A | Super precision tolerance class, exceeding ABEC 7/ISO P4 standards. Ensures extremely tight running accuracy for the most demanding applications. |
S7016 CDGA/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The P4A tolerance class and extra light preload (Class A) ensure minimal runout and exceptional shaft stability, which is critical for achieving high surface finishes and machining accuracy.
- Superior High-Speed Performance: The combination of hybrid ceramic balls and a lightweight phenolic resin cage reduces centrifugal forces and operating temperatures, enabling a high limiting speed of 28,000 rpm.
- Enhanced Load Capacity: The 15° contact angle is optimized to handle substantial 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 reliable performance under strenuous conditions.
- Reduced Maintenance & Long Life: The bearing comes sealed and pre-lubricated with grease, protecting against contamination and providing long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
S7016 CDGA/HCP4A Bearing Typical Application Areas
The S7016 CDGA/HCP4A is specifically designed for high-end, precision-driven applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- High-Frequency Motors and Spindles: Where low inertia and high rotational accuracy are paramount.
- Medical and Dental Equipment: High-speed handpieces and imaging scanners.
- Aerospace and Defense Systems: Gyroscopes, radar systems, and other critical instrumentation.
