7016 ACD/P4ATFTA Bearing Product Overview & Core Advantages
The 7016 ACD/P4ATFTA is a precision angular contact ball bearing designed for the most demanding applications. Engineered as part of a triplex face-to-face (TFT) matched set, it delivers exceptional system rigidity and stability. Its defining characteristic is the ability to handle significant combined loads—both radial and axial—simultaneously, making it an ideal choice for high-precision, high-reliability machinery where uncompromising accuracy and high rigidity are paramount. Manufactured to the stringent P4A tolerance class, this bearing ensures superior running accuracy and consistent performance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Standard bearing series with 80 mm bore and 125 mm outside diameter. |
| AC | Angular Contact design with a 25° contact angle. |
| D | Signifies a duplex (two-bearing) configuration, which is used to create the triplex set. |
| P4A | Indicates a high-precision tolerance class with enhanced running accuracy and dimensional stability. |
| TFT | Specifies the Triplex Face-to-Face matched arrangement of three bearings. |
| A | Denotes an Extra Light Preload for minimal friction and optimal high-speed operation. |
7016 ACD/P4ATFTA Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The triplex face-to-face arrangement creates an exceptionally stiff bearing system, crucial for applications requiring minimal deflection under heavy combined loads.
- Superior Load Capacity: The 25° contact angle and robust construction provide excellent capacity for both radial and axial loads, ensuring reliable operation in demanding conditions.
- High-Speed Capability: The phenolic cage offers low weight and excellent high-speed characteristics, contributing to a limiting speed of 28,000 rpm. The extra light preload (Class A) further minimizes friction and heat generation.
- Precision Performance: Manufactured to P4A tolerance standards, this bearing guarantees tight dimensional control and superior running accuracy, which is essential for precision spindles and machinery.
- Optimized Material Selection: Components made from chrome steel provide high hardness, wear resistance, and a long operational lifespan.
