S7016 ACDGA/P4A Bearing Product Overview & Core Advantages
The S7016 ACDGA/P4A is a high-precision, double-row angular contact ball bearing designed for applications demanding exceptional rigidity and accuracy. Engineered to simultaneously handle combined radial and axial loads from both directions, its compact design makes it ideal for high-speed spindles and other precision machinery. Manufactured to the stringent P4A tolerance class, this bearing ensures superior running accuracy, low noise, and high operational reliability, making it a cornerstone component for advanced industrial equipment.
S7016 ACDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| AC | Angular Contact | Optimized for combined loads. |
| D | Double Row | Provides high rigidity and increased load capacity. |
| GA | Light Preload | Reduces deflection, enhances shaft positioning accuracy and system stiffness. |
| P4A | Tolerance Class | Denotes ultra-precision dimensional and running accuracy, superior to ABEC 7. |
S7016 ACDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row design and 25° contact angle provide superior resistance to moment loads and enable the bearing to support significant combined radial and axial loads in both directions, ensuring stable operation under demanding conditions.
- Precision & High-Speed Performance: The phenolic resin cage offers excellent strength-to-weight ratio, reduced friction, and is ideal for high-speed operation, contributing to the bearing's high limiting speed. The P4A precision guarantees minimal runout and vibration.
- Sealed & Ready-to-Use: As a sealed bearing, it is pre-lubricated with grease, protecting against contamination and providing a long service life without the need for re-lubrication in many applications. This makes it a maintenance-free solution.
- Universal Matching (SU): This bearing is "universally matchable," meaning any two bearings can be paired in a duplex set without selective assembly, simplifying installation and ensuring optimal preload and performance.
S7016 ACDGA/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Grinding Spindles
- High-Frequency Motors
- Industrial Pumps and Compressors
- Medical and Laboratory Equipment
- Robotic Arms and Precision Gearboxes
