7016 CD/P4ADBA Bearing Product Overview & Core Advantages
The 7016 CD/P4ADBA is a duplex back-to-back (DB) matched pair of precision angular contact ball bearings, designed for applications demanding exceptional rotational accuracy and rigidity. This P4A tolerance class bearing is preloaded to Extra Light (Class A), ensuring minimal runout and stable performance under high-speed operation. Its core advantage lies in its ability to support combined loads (radial and axial) simultaneously with high precision, making it an ideal choice for high-precision spindles and other critical machinery components.
7016 CD/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing designation indicating a 80 mm bore, 125 mm OD, and 44 mm width. |
| C | Designates a 15° contact angle. |
| D | Indicates the bearing is part of a duplex pair. |
| P4A | Specifies the tolerance class for high precision, with enhanced running accuracy requirements. |
| DB | Specifies the matched arrangement as Back-to-Back. This configuration provides high moment rigidity. |
| A | Indicates the preload level is Extra Light (Class A). |
7016 CD/P4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Moment Load Capacity: The duplex back-to-back (DB) arrangement creates a wide effective spread, significantly increasing the bearing's resistance to moment loads and providing exceptional system rigidity.
- Optimized for Combined Loads: The 15° contact angle is engineered to efficiently support substantial radial loads alongside axial loads in both directions.
- High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 28,000 rpm. The open design and factory-applied lubrication are optimized for heat dissipation.
- Precision & Accuracy: Manufactured to P4A tolerance class with very tight dimensional tolerances on the bore, outside diameter, and width, ensuring superior running accuracy essential for precision applications.
- Premium Materials: Constructed from chrome steel for both rings and balls, offering high hardness, wear resistance, and long service life.
7016 CD/P4ADBA Bearing Typical Application Areas
This high-precision, high-rigidity bearing is specifically designed for demanding applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving machines, and other high-speed automated equipment.
- High-Frequency Motors: Where low vibration and high running accuracy are critical.
- Medical Equipment: High-speed centrifuges and dental handpieces.
- Robotics: Precision joints and arm assemblies requiring high rigidity.
