7002 ACD/P4ADGB Bearing Product Overview & Core Advantages
The 7002 ACD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing in P4A tolerance class, it is engineered to handle combined radial and axial loads simultaneously. Its optimized design, featuring a 25° contact angle and light preload (Class B), ensures high running accuracy, excellent high-speed capability, and stable performance in precision machinery and spindle applications.
7002 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| ACD | 25° Contact Angle | Optimized for handling significant axial loads in both directions while maintaining radial load capacity. |
| P4A | High Precision Tolerance Class | Superior dimensional and running accuracy, ensuring minimal vibration and high positional precision. |
| DGB | Universal Matchable (SU) Pair | Two bearings are manufactured to be universally matchable, allowing flexible mounting configurations (DB, DF, DT) without pre-selection. |
7002 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design with a 25° contact angle provides high rigidity, enabling the bearing to withstand substantial combined loads (radial and axial). The light preload (Class B) eliminates internal clearance, enhancing system stiffness and rotational accuracy.
- Superior High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 95,000 rpm. This makes it ideal for high-speed spindle applications.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore and OD tolerance: -0.004mm to 0), this bearing ensures exceptional running accuracy and minimal rotational vibration.
- Universal Matching Capability (SU): As a universal matchable bearing, any two bearings can be paired in various arrangements (back-to-back, face-to-face, or tandem) without the need for selective assembly, simplifying installation and inventory management.
7002 ACD/P4ADGB Bearing Typical Application Areas
The 7002 ACD/P4ADGB is ideally suited for high-precision, high-speed applications where accuracy and rigidity are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- Medical Equipment: Dental handpieces, centrifuges, and scanner rotors.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- High-Frequency Motors and Spindles: Where low vibration and high rotational accuracy are required.
