7016 CE/P4ADGA Bearing Product Overview & Core Advantages
The 7016 CE/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. This universal matchable bearing is part of a matched set of two, allowing for simplified assembly and optimal preload configuration. Engineered with a P4A tolerance class and an extra light preload (Class A), it delivers superior running accuracy and high-speed capabilities, making it ideal for high-precision spindles and other demanding machinery.
7016 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| CE | Indicates a universal matchable bearing designed to be paired with another identical bearing in a back-to-back (DB) or face-to-face (DF) arrangement. |
| P4A | Denotes a high-precision tolerance class with enhanced dimensional and running accuracy, exceeding standard ABEC 7/ISO P4 levels. |
| DGA | Signifies the preload level. In this case, Class A represents an extra light preload, optimized for very high speeds and minimal friction. |
7016 CE/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design with a 15° contact angle enables the bearing to efficiently support combined radial and axial loads. When used as a universally matched pair, the arrangement provides significantly increased system rigidity and moment load capacity.
- Superior High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, while the extra light preload reduces friction and heat generation. This combination allows for a high limiting speed of 28,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance class with tight bore and outside diameter tolerances, this bearing ensures exceptional running accuracy, reduced vibration, and extended service life in precision applications.
- Optimized Internal Geometry: The design features 25 high-grade chrome steel balls with a diameter of 11.112 mm, precisely configured to maximize load distribution and performance.
