7016 CD/P4ATBTA Bearing Product Overview & Core Advantages
The 7016 CD/P4ATBTA is a precision angular contact ball bearing designed for the most demanding applications requiring exceptional accuracy and rigidity. As part of a Triplex Back-to-Back (TBT) matched set, this bearing configuration delivers superior stiffness and stability, making it ideal for handling combined loads (radial and axial) simultaneously. Manufactured to a P4A tolerance class and featuring an Extra light (Class A) preload, it ensures high rotational accuracy and minimal runout, which is critical in high-speed, high-precision machinery.
7016 CD/P4ATBTA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Standard bearing series designation, with 80 mm bore and 125 mm outside diameter. |
| C | Specifies a 15° contact angle, optimized for high-speed operation and axial load capacity. |
| D | Indicates the bearing is part of a matched set for specific preload and performance characteristics. |
| P4A | Denotes a high-precision tolerance class with extremely tight dimensional and running accuracy limits. |
| TBT | Specifies the Triplex Back-to-Back arrangement of three bearings in the matched set. |
| A | Indicates an Extra light preload (Class A) for minimal friction and optimal high-speed performance. |
7016 CD/P4ATBTA Bearing Structural Features & Performance Benefits
High Rigidity & Stability: The Triplex Back-to-Back (TBT) arrangement of three bearings creates an exceptionally rigid system that resists moment loads and maintains shaft positioning under heavy combined loads.
Superior Load Capacity: The angular contact design with a 15° contact angle efficiently supports substantial radial loads and axial loads in one direction. The matched set multiplies this capability for the entire assembly.
High-Speed Performance: The phenolic cage is lightweight and robust, contributing to lower centrifugal forces and smooth operation at the high limiting speed of 28,000 rpm. The Extra light preload further minimizes heat generation at high speeds.
Precision Engineering: Manufactured to P4A tolerance standards with tight bore, outside diameter, and width tolerances, this bearing guarantees high running accuracy, reduced vibration, and extended service life in precision applications.
