S7206 ACD/HCP4ADGC Bearing Product Overview & Core Advantages
The S7206 ACD/HCP4ADGC is a high-precision double row angular contact ball bearing engineered for demanding applications. Its core advantage lies in its ability to simultaneously handle combined loads—significant radial and bidirectional axial loads—with high rigidity and exceptional running accuracy. The combination of a ceramic ball material and a P4A super-precision tolerance class ensures superior performance in high-speed and high-reliability scenarios. Its sealed and pre-greased design offers long-term, maintenance-free operation.
S7206 ACD/HCP4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7206 | Basic bearing designation, indicating a double row angular contact ball bearing with a 30mm bore. |
| ACD | Contact angle of 25°. |
| HC | Hybrid Ceramic, signifying ceramic balls for reduced weight, higher speed capability, and longer service life. |
| P4A | Super-precision tolerance class, exceeding ABEC 7/ISO P4 standards for enhanced running accuracy. |
| DGC | Designates a sealed bearing, pre-lubricated with grease. |
S7206 ACD/HCP4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial rigidity, enabling stable operation under combined loads. The 25° contact angle is optimized for supporting substantial bidirectional axial forces.
- Exceptional High-Speed Performance: The lightweight phenolic cage and hybrid ceramic balls significantly reduce centrifugal forces, allowing for a high limiting speed of 100,500 rpm. This makes it an ideal high-speed bearing.
- Precision & Longevity: Manufactured to P4A tolerance for minimal runout and vibration. The sealed construction with factory-applied grease protects against contamination and provides a wide operating temperature range (-30°C to 110°C), ensuring long service life with minimal maintenance.
- Universal Matchability (SU): Bearings are universally matchable, allowing for flexible mounting in pairs (back-to-back, face-to-face, or tandem) to create a preloaded bearing set for maximum system stiffness.
S7206 ACD/HCP4ADGC Bearing Typical Application Areas
