7206 ACD/P4ADGA Bearing Product Overview & Core Advantages
The 7206 ACD/P4ADGA is a super-precision double row angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. Its design is optimized to simultaneously support combined radial and axial loads from both directions. Featuring an Extra Light (A) preload and a P4A tolerance class, this bearing delivers high running accuracy, excellent speed capability, and stable performance in high-precision systems. Its universal matchable (SU) design allows for flexible mounting arrangements, simplifying installation and enhancing operational reliability.
7206 ACD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle. |
| D | Double row bearing configuration. |
| P4A | High precision tolerance class (superior to ABEC 7), ensuring minimal runout and vibration. |
| DGA | Universal Matchable (SU) bearing set. Two bearings are supplied as a universally matchable pair for simplified mounting in various configurations (DB, DF, DT). |
7206 ACD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and 25° contact angle provide high radial and axial rigidity, enabling the bearing to effectively handle combined loads and moment loads.
- Super-Precision Performance: Manufactured to P4A tolerance class with extremely tight dimensional tolerances, this bearing guarantees high running accuracy, low noise, and minimal heat generation.
- Optimized High-Speed Capability: The lightweight phenolic resin cage and optimized internal geometry contribute to a high limiting speed of 100,500 rpm, making it suitable for high-speed spindles.
- Universal Matching & Simplified Assembly: The Universal Matchable (SU) feature allows the two supplied bearings to be mounted in any preload configuration (face-to-face, back-to-back, or tandem) without selective assembly, reducing installation time and complexity.
- Premium Material Construction: Made from high-grade chrome steel for rings and balls, ensuring long service life and consistent performance under demanding conditions.
