S7016 ACD/HCP4ADGA Bearing Product Overview & Core Advantages
The S7016 ACD/HCP4ADGA is a precision double-row angular contact ball bearing engineered for applications demanding exceptional accuracy, rigidity, and speed. Its design enables it to simultaneously support substantial combined loads (radial and bidirectional axial loads), making it ideal for high-performance machinery. Featuring a universal matchable (SU) design, two bearings can be paired in any combination to achieve the required preload and stiffness. With a P4A super-precision tolerance class and ceramic balls, this bearing delivers superior rotational accuracy, extended service life, and reliable operation in demanding conditions.
S7016 ACD/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| S7016 | Bearing Series & Size | Denotes a 7000-series, 80mm bore, 125mm OD, 44mm width double-row angular contact ball bearing. |
| ACD | 25° Contact Angle | Optimized for high axial load capacity and high-speed performance. |
| HC | Hybrid Ceramic | Indicates the use of ceramic balls, which reduce friction, heat generation, and wear, enabling higher speeds and longer life. |
| P4A | Tolerance Class | Specifies super-precision dimensional and running accuracy, superior to ABEC 7/ISO P4. |
| DGA | Sealed & Grease Lubricated | Signifies that the bearing is sealed and factory-filled with a specific high-performance grease, offering protection from contamination and providing long-term, maintenance-free operation. |
S7016 ACD/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row design and 25° contact angle provide exceptional stiffness and the ability to handle significant combined radial and axial loads from both directions, ensuring stable shaft positioning.
- Superior High-Speed Performance: The combination of a lightweight phenolic cage, low-friction ceramic balls, and optimized internal geometry allows for a high limiting speed of 28,000 rpm, minimizing centrifugal forces and operational temperatures.
- Precision & Longevity: Manufactured to P4A tolerance standards with universal matching (SU), this bearing guarantees minimal runout and vibration. The hybrid ceramic construction significantly enhances service life, especially in challenging environments.
- Maintenance-Free Operation: The integrated seals and pre-applied grease lubrication effectively exclude contaminants and retain lubricant, making the bearing ready for installation and capable of long-term, reliable performance within its specified temperature range.
