7006 ACD/P4ADGA Bearing Product Overview & Core Advantages
The 7006 ACD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing excels in handling combined loads—simultaneously supporting significant radial loads and axial loads in one direction. Its universal matchable (SU) design allows for flexible mounting arrangements in pairs, enabling optimal preload control for enhanced system stiffness. The phenolic cage and precision-ground components contribute to its superior high-speed performance, making it an ideal choice for high-precision machinery where reliability and accuracy are paramount.

| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| AC | Angular Contact (25° contact angle) | Optimized for combined radial and axial loads |
| D | Universal Matchable (SU designation) | Enables flexible pairing for precise preload configuration |
| P4A | High Precision Tolerance Class | Exceptional running accuracy and dimensional stability |
| GA | Light Preload | Reduced friction while maintaining system rigidity |
7006 ACD/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with 25° contact angle provides optimal stress distribution, enabling the bearing to handle combined loads efficiently. The universal matching capability allows for precise preload adjustment when mounted in pairs, significantly enhancing system stiffness.
High-Speed Performance: The phenolic cage offers excellent strength-to-weight ratio and smooth operation at high rotational speeds. Combined with precision-ground raceways and 14 high-quality chrome steel balls, the bearing achieves a limiting speed of 53,000 rpm.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore diameter tolerance: -0.004mm to 0), this bearing ensures minimal runout and vibration, making it suitable for applications requiring exceptional rotational accuracy.
Material Excellence: Constructed from chrome steel for both rings and balls, the bearing delivers superior wear resistance and fatigue life, operating reliably within a temperature range of -30°C to 110°C.
