7006 CD/P4ADBA Bearing Product Overview & Core Advantages
The 7006 CD/P4ADBA is a precision duplex angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This matched set of two bearings, arranged in a Back-to-Back (DB) configuration, is preloaded to Extra light (Class A) specifications, ensuring minimal axial and radial play for superior running precision. Its primary advantage lies in its ability to handle combined loads—significant radial loads alongside substantial axial loads in both directions—making it an ideal solution for high-speed, high-rigidity spindles and precision machinery.
7006 CD/P4ADBA 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-speed operation and moderate axial load capacity. |
| D | Indicates the bearing is part of a duplex (matched) set. |
| P4A | Denotes a high-precision tolerance class with enhanced running accuracy, tighter than ABEC 7. |
| DB | Specifies the Back-to-Back arrangement of the matched pair, providing high moment rigidity. |
| A | Indicates the Extra light preload level, minimizing friction and heat generation at high speeds. |
7006 CD/P4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex Back-to-Back (DB) arrangement creates a wide, rigid support system that effectively resists moment loads and shaft deflection, ensuring exceptional operational stability.
- Superior Precision: Manufactured to P4A tolerance class, this bearing guarantees minimal runout and vibration, which is critical for applications requiring extreme accuracy.
- Optimized High-Speed Performance: The 15° contact angle and lightweight phenolic cage reduce centrifugal forces and friction, enabling a high limiting speed of 56,000 rpm. The Extra light preload further enhances high-speed capability by controlling ball skidding.
- Robust Load Capacity: The angular contact design allows it to support significant combined radial and axial loads simultaneously. The dynamic load rating of 5265 lbf confirms its durability under demanding conditions.
- Pre-Lubricated for Immediate Use: The bearing comes lubricated from the factory, ready for installation and ensuring optimal performance from start-up.
7006 CD/P4ADBA Bearing Typical Application Areas
This precision duplex bearing is engineered for high-performance applications where accuracy, speed, and rigidity are paramount. Key sectors include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving machines, and high-frequency motors.
- Robotics: High-accuracy joints and arm assemblies.
- Medical Equipment: Dental handpieces and laboratory instrumentation.
- Aviation & Aerospace: Gyroscopes, navigation systems, and auxiliary power units.
