S7016 ACD/P4ADBC Bearing Product Overview & Core Advantages
The S7016 ACD/P4ADBC is a precision duplex angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This matched back-to-back (DB) arrangement is preloaded to Moderate / Class C specifications, delivering superior rotational stability and stiffness. Engineered to handle combined radial and axial loads simultaneously, it is an ideal solution for high-speed spindles and precision machinery where uncompromising performance is critical. Its compact design and P4A tolerance class ensure high running accuracy and reliability.
S7016 ACD/P4ADBC Bearing Model Code Explained, Specifications & Naming Convention
- S7016: Basic bearing series, indicating a 80mm bore, 125mm OD, and 44mm width.
- A: Denotes a 25° contact angle, optimized for supporting high axial loads.
- CD: Specifies a duplex pair in a Back-to-Back (DB) arrangement.
- P4A: Indicates an ultra-high precision tolerance class, exceeding standard ABEC 7/ISO P4 levels for enhanced running accuracy.
- DBC: Specifies the preload level within the duplex set; here, Moderate / Class C preload for optimal rigidity and speed performance.
S7016 ACD/P4ADBC Bearing Structural Features & Performance Benefits
High Rigidity & Stability: The duplex back-to-back (DB) configuration and moderate preload create a highly rigid bearing system that effectively resists moment loads and maintains precise shaft positioning under complex loading conditions.
Superior Load Capacity: With a 25° contact angle and robust construction, this bearing excels at handling combined radial and axial loads. The dynamic load rating of 22,725 lbf and static load rating of 26,100 lbf ensure long service life in demanding applications.
Optimized High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces, while the precision P4A grading ensures smooth operation. This contributes to a high limiting speed of 28,000 rpm.
Precision & Reliability: Manufactured to P4A tolerance class with tight dimensional control on bore, OD, and width, this bearing guarantees exceptional running accuracy, low vibration, and consistent performance.
S7016 ACD/P4ADBC Bearing Typical Application Areas
This high-precision duplex bearing is ideally suited for:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Gearboxes and Transmission Systems
- High-Frequency Motors and Spindle Drives
- Industrial Pumps and Compressors
