7006 CD/P4ADBBGMM Bearing Product Overview & Core Advantages
The 7006 CD/P4ADBBGMM is a precision duplex angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This metric system bearing features a back-to-back (DB) matched arrangement and a Light (Class B) preload, enabling it to withstand combined radial and axial loads simultaneously. Manufactured to a P4A tolerance class, it offers superior running accuracy, making it ideal for high-speed, high-reliability spindles and precision machinery. Its compact design and optimized internal geometry contribute to outstanding operational stability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD, 26mm width). |
| C | 15° contact angle, optimized for high-speed performance and moderate axial load capacity. |
| D | Signifies a duplex pair of bearings. |
| P4A | Indicates high precision tolerance class, exceeding ABEC 7 standards for enhanced running accuracy. |
| DB | Specifies the back-to-back mounting arrangement, providing high moment rigidity. |
| BG | Indicates the specific preload grade: Light preload (Class B). |
| MM | Denotes the bearing is supplied as a universally matched set for immediate installation without further adjustment. |
7006 CD/P4ADBBGMM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement creates a wide effective spread, significantly increasing the bearing's resistance to moment loads and providing high system rigidity. This configuration efficiently handles combined radial and axial loads from both directions.
- Superior High-Speed Performance: The 15° contact angle and lightweight phenolic resin cage reduce centrifugal forces and friction, enabling stable operation at the high limiting speed of 56,000 rpm. The open seal type minimizes friction for maximum speed capability.
- Precision & Accuracy: Manufactured to P4A tolerance class with tight dimensional controls on bore, outside diameter, and width, this bearing ensures minimal runout and vibration for applications requiring extreme precision.
- Optimized Material Selection: Components made from chrome steel for both rings and balls provide high hardness, wear resistance, and long service life under demanding conditions.
7006 CD/P4ADBBGMM Bearing Typical Application Areas
This bearing is engineered for high-performance applications, including:
- 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 rotary actuators.
- Medical Equipment: Dental handpieces, centrifuges, and imaging scanner rotors.
- Aerospace & Defense Systems: Gyroscopes, radar platforms, and guidance systems.
