7016 CD/P4A Bearing Product Overview & Core Advantages
The 7016 CD/P4A is a single-row angular contact ball bearing engineered for applications demanding high precision and superior rotational accuracy. Designed to accommodate primarily axial loads in one direction and combined loads, its 15° contact angle provides an optimal balance between load capacity and speed capability. Manufactured to P4 (ABEC-7) tolerance class, this bearing ensures exceptional running accuracy and is preloaded for enhanced system rigidity and reduced vibration in high-performance machinery.
7016 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing series and size designation (80mm bore, 125mm OD, 22mm width). |
| CD | Indicates a specific contact angle (15°) and internal design optimized for high rigidity. |
| P4A | Denotes a P4 (ABEC-7) tolerance class with specific running accuracy requirements and preload applied. |
7016 CD/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The P4 tolerance class and application of preload significantly increase system stiffness, minimize axial and radial play, and ensure precise shaft positioning, which is critical for applications like machine tool spindles.
- Optimized Load Capacity: The 15° contact angle is engineered to efficiently handle high axial loads in one direction as well as combined (radial and axial) loads.
- High-Speed Capability: The lightweight and robust phenolic resin cage ensures stable operation and guides the balls effectively, contributing to the high limiting speed of 17,000 rpm.
- Durable Material Construction: Components made from chrome steel offer high hardness, wear resistance, and a long operational life under demanding conditions.
7016 CD/P4A Bearing Typical Application Areas
This high-precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles (milling, grinding, and lathe applications)
- High-Frequency Motors and Precision Gearboxes
- Industrial Pumps and Compressors
- Aerospace Positioning Systems and Medical Equipment
