7006 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7006 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. As a universal matchable (SU) bearing, it can be paired with another identical bearing in various configurations to achieve specific preload and rigidity requirements. Its P4A tolerance class ensures superior dimensional and running accuracy, making it ideal for high-precision spindles and other critical machinery components. The combination of a 15° contact angle and extra light preload (Class A) provides optimal performance for handling combined radial and axial loads simultaneously.
7006 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD, 26mm width) |
| CD | Contact angle of 15° |
| P4A | High precision tolerance class for enhanced running accuracy |
| DGA | Universal matchable bearing (SU designation) in a duplex arrangement |
7006 CD/P4ADGA Bearing Structural Features & Performance Benefits
This bearing's performance stems from its optimized construction. The phenolic cage contributes to lower friction and higher limiting speeds (up to 100,500 rpm), making it an excellent high-speed bearing. The 15° contact angle is engineered to handle combined loads effectively, providing stable operation under both radial and axial forces. Manufactured to P4A precision standards with tight dimensional tolerances, it ensures minimal runout and vibration. The universal matchable (SU) design allows for flexible mounting arrangements, enabling engineers to achieve desired preload and high rigidity without selective matching.
