S7016 ACDGA/HCP4A Bearing Product Overview & Core Advantages
The S7016 ACDGA/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional speed, rigidity, and accuracy. As a single bearing with a 25° contact angle and Extra Light (A) preload, it is optimized to handle combined loads—significant radial and axial loads simultaneously. Its construction with a phenolic cage and ceramic balls enables superior high-speed performance and reduced rotational mass. Manufactured to a P4A tolerance class, this bearing guarantees ultra-precise running accuracy, making it an ideal component for high-reliability spindles and precision machinery.
Model Code Breakdown
- S7016: Basic bearing series and size designation (80mm bore, 125mm OD).
- AC: Angular Contact design.
- D: High-precision phenolic (textile) cage.
- GA: Preload specification (Extra Light / Class A).
- HC: Hybrid Ceramic construction (Ceramic balls with steel rings).
- P4A: Tolerance class denoting very high running accuracy and dimensional precision.
S7016 ACDGA/HCP4A Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The 25° contact angle and robust internal geometry are designed to provide high rigidity, effectively supporting combined radial and axial loads in high-speed applications.
Superior High-Speed Performance: The combination of a lightweight phenolic cage and low-density ceramic balls significantly reduces centrifugal forces, allowing for a high limiting speed of 28,000 rpm. This hybrid construction also minimizes heat generation.
Precision and Longevity: Manufactured to P4A tolerance standards, this bearing ensures minimal runout and vibration. The standard grease lubrication and sealed design contribute to maintenance-free operation within a wide temperature range of -30°C to 110°C.
