S7016 ACD/P4A Bearing Product Overview & Core Advantages
The S7016 ACD/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Positioned in the P4 (ABEC-7) tolerance class, it guarantees minimal dimensional runout, making it ideal for high-speed spindles and precision machinery. A key advantage is its ability to accommodate combined radial and axial loads simultaneously, thanks to its defined 25° contact angle. The bearing is preloaded, enhancing system stiffness and rotational accuracy, and comes sealed and pre-lubricated for immediate installation and long-term, maintenance-free operation.
S7016 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Indicates a 25° contact angle and that the bearing is supplied with a specific preload for high rigidity and precise operation. |
| P4A | Denotes a very high tolerance class (P4 / ABEC-7) with additional requirements for running accuracy. |
S7016 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a 25° contact anglepreload ensures high system stiffness, minimizing deflection under load and maintaining exceptional rotational accuracy, which is critical for machining quality.
- Superior Load Capacity: Designed to handle significant combined radial and axial loads. With a dynamic load rating of 14,040 lbf and a static load rating of 13,162 lbf, it offers reliable performance in demanding applications.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 9,500 rpm. The precision-ground chrome steel rings and balls ensure smooth, low-vibration operation at high rotational speeds.
- Sealed and Ready-to-Use: The sealed design effectively excludes contaminants, while the factory-applied lubrication ensures immediate operation and long service life within a temperature range of -30°C to 110°C.
S7016 ACD/P4A Bearing Typical Application Areas
This bearing is specifically designed for high-performance machinery where precision and speed are paramount. Key application areas include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles: Applications requiring extreme rotational accuracy and minimal runout.
- High-Frequency Motors and Spindles: Where high rotational speeds and rigidity are essential.
- Medical and Dental Equipment: High-speed handpieces and diagnostic scanners.
- Aerospace and Defense Systems: Gyroscopes, radar systems, and other precision instruments.
