7007 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7007 CD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. As a universal matchable (SU) bearing supplied in a pre-loaded duplex set, it is engineered to handle combined radial and axial loads simultaneously. Its P4A tolerance class ensures ultra-precision operation, making it ideal for high-speed spindles and other critical machinery where high rigidity and minimal runout are paramount.
7007 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Indicates a duplex bearing set with a specific contact angle arrangement (typically back-to-back or face-to-face) for optimized load handling. |
| P4A | Denotes an ultra-precision tolerance class with enhanced dimensional and running accuracy, exceeding ABEC 7 standards. |
| DGB | Signifies a universal matchable (SU) bearing. Two such bearings can be paired in any combination (back-to-back, face-to-face, or tandem) to achieve the desired preload and stiffness without selective mounting. |
7007 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex set configuration and 15° contact angle provide superior stiffness, enabling the bearing to withstand significant combined loads (radial and axial) with minimal deflection.
- Precision & High-Speed Performance: Manufactured to P4A tolerance standards and featuring a lightweight phenolic cage, this bearing ensures smooth operation and is capable of achieving a high limiting speed of 56,000 rpm, making it a true high-speed bearing.
- Optimized Material Selection: Constructed from chrome steel for both rings and balls, the bearing offers high durability and wear resistance. The phenolic cage contributes to lower friction and is suitable for high-speed applications.
- Universal Matchability (SU): The DGB suffix guarantees that any two bearings from the same lot can be universally matched, simplifying installation and ensuring consistent, predictable performance in preloaded arrangements.
7007 CD/P4ADGB Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Robotic Arm Joints and Precision Gearboxes
