S7016 ACDTP/P4B Bearing Product Overview & Core Advantages
The S7016 ACDTP/P4B is a precision single-row angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. Manufactured to P4 (ABEC-7) tolerance class, it offers superior dimensional stability and running accuracy. Its key advantage lies in its ability to accommodate combined loads, efficiently handling significant radial loads and thrust loads in one direction simultaneously. The bearing comes preloaded and pre-lubricated, ensuring high rigidity and immediate operational readiness, making it an ideal choice for high-reliability, high-precision machinery.
S7016 ACDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| S7016 | Basic bearing series and size designation (80mm bore, 125mm OD, 22mm width). |
| AC | Angular Contact design with a 25° contact angle for optimal thrust capacity. |
| DT | Matched set of two bearings in a Tandem (DT) arrangement to increase thrust capacity in one direction. |
| P | Indicates that the bearing is supplied with a preload for enhanced rigidity and precise shaft positioning. |
| P4B | Specifies the tolerance class P4 (ABEC-7), denoting very high precision levels for critical applications. |
S7016 ACDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row angular contact design combined with a P4 precision grade and factory-applied preload ensures maximum system stiffness and minimal runout, which is critical for machining accuracy.
- Superior Load Capacity: Engineered with a 25° contact angle and high-grade chrome steel components, this bearing delivers excellent radial and one-directional thrust load ratings (14,040 lbf dynamic / 13,162 lbf static).
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, enabling stable operation at high limiting speeds (9,500 rpm). The pre-applied lubrication further ensures reliable performance at these speeds.
- Sealed and Lubricated for Life: As a sealed and pre-lubricated unit, it is protected from contamination and is ready for immediate installation, offering long service life with minimal maintenance.
S7016 ACDTP/P4B Bearing Typical Application Areas
The S7016 ACDTP/P4B is ideally suited for high-performance applications where precision, speed, and rigidity are paramount. Key sectors include:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers.
- Precision Spindles: In PCB drilling, engraving machines, and other high-precision equipment.
- High-Frequency Motors: Where high rotational speeds and accuracy are required.
- Industrial Pumps and Compressors: For handling significant axial and radial loads efficiently.
