7016 CD/P4ADT Bearing Product Overview & Core Advantages
The 7016 CD/P4ADT is a precision angular contact ball bearing configured as a Duplex Tandem (DT) matched set. Engineered for high-precision and high-rigidity applications, this bearing is designed to accommodate high axial loads in one direction. Its P4A tolerance class ensures exceptional running accuracy, making it ideal for demanding applications requiring superior performance and reliability. The duplex tandem arrangement significantly increases axial load capacity and system rigidity compared to a single bearing.
7016 CD/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing series and size designation (80mm bore, 125mm OD, 44mm width). |
| C | Designates a 15° contact angle, optimized for high axial load capacity. |
| D | Indicates the bearing is part of a Duplex (matched pair) set. |
| P4A | Specifies a high-precision tolerance class, exceeding ABEC 7/ISO P4 standards, for superior running accuracy. |
| DT | Defines the Duplex Tandem arrangement, where two bearings are mounted to face the same direction to maximize axial load capacity in that direction. |
7016 CD/P4ADT Bearing Structural Features & Performance Benefits
High Rigidity & Axial Load Capacity: The duplex tandem (DT) arrangement combines two bearings to create an exceptionally rigid assembly capable of supporting very high axial loads. The 15° contact angle is specifically chosen to maximize this axial load performance.
Precision Performance: Manufactured to P4A tolerance class, this bearing guarantees minimal runout and vibration, which is critical for high-speed and high-precision applications. The tight dimensional tolerances on the bore, outside diameter, and width ensure predictable and reliable performance.
High-Speed Capability: The lightweight and robust phenolic resin cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 28,000 rpm. This makes the bearing suitable for demanding high-speed spindle applications.
Material & Lubrication: Constructed from high-grade chrome steel for both rings and balls, the bearing offers excellent durability and fatigue life. It is supplied lubricated and ready for installation, operating effectively within a temperature range of -30°C to 110°C.
7016 CD/P4ADT Bearing Typical Application Areas
The 7016 CD/P4ADT is ideally suited for high-performance machinery where precision, rigidity, and high axial load capacity are paramount. Key application areas include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling machines and other high-precision automated equipment.
- High-Frequency Motors: Spindles for applications requiring extreme rotational accuracy.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and other precision instruments.
