7016 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7016 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high rigidity. Manufactured to P4A tolerance class, this bearing excels in high-speed scenarios with a limiting speed of 28,000 rpm. Its universal matchable (SU) design allows for flexible mounting in duplex arrangements (DB, DF, DT) to optimize preload and system stiffness, making it ideal for supporting combined loads (radial and axial) in both directions. The phenolic cage and superior chrome steel construction contribute to its reliable performance in a wide temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing series, indicating a 80 mm bore, 125 mm OD, and 44 mm width. |
| CD | Specifies a 15° contact angle and indicates the bearing is designed for universal matching (SU). |
| P4A | Denotes a high-precision tolerance class with enhanced running accuracy and dimensional stability. |
| DGA | Indicates the bearing is lubricated and supplied as part of a universally matchable pair (2 bearings in set). |
7016 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and universal matching capability enable the bearing to be preloaded in pairs, significantly increasing system rigidity. It can efficiently support combined radial and axial loads from both directions, with a dynamic load rating of 23,850 lbf and a static load rating of 27,450 lbf.
- High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the 15° contact angle and precision grinding contribute to stable operation at high speeds up to 28,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration, which is critical for applications requiring high rotational accuracy.
- Optimized Material: Constructed from high-grade chrome steel for both rings and balls, providing excellent durability and wear resistance.
