7006 CD/P4ADT Bearing Product Overview & Core Advantages
The 7006 CD/P4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This duplex tandem (DT) arrangement bearing set is preloaded and manufactured to P4A tolerance class, ensuring ultra-precise rotational accuracy and minimal runout. Its primary advantage lies in its ability to handle high axial loads in one direction with superior rigidity, making it an ideal solution for high-speed spindles and precision machinery where uncompromising performance is critical.
7006 CD/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing designation indicating a 30mm bore, 55mm OD, and 26mm width. |
| C | Specifies a 15° contact angle, optimized for high axial load capacity. |
| D | Indicates the bearing is supplied as a duplex pair. |
| P4A | Denotes a high-precision tolerance class with enhanced dimensional and running accuracy. |
| DT | Signifies a Duplex Tandem arrangement, where two bearings are mounted together to increase axial load capacity in the same direction. |
7006 CD/P4ADT Bearing Structural Features & Performance Benefits
High Rigidity & Axial Load Capacity: The duplex tandem arrangement and 15° contact angle create an exceptionally rigid system capable of supporting high unidirectional axial loads, minimizing shaft deflection under load.
Precision Performance: Manufactured to P4A tolerance class with a phenolic cage, this bearing ensures smooth operation, reduced vibration, and superior running accuracy, which is critical for high-speed applications.
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 very high-speed spindle applications.
Preloaded & Ready-to-Mount: The bearings are supplied as a pre-matched and preloaded set, simplifying installation and ensuring immediate, optimal performance without the need for complex adjustment.
