7030 ACD/P4ADGB Bearing Product Overview & Core Advantages
The 7030 ACD/P4ADGB is a precision angular contact ball bearing designed for high-performance applications requiring exceptional rotational accuracy and rigidity. Engineered to a P4A tolerance class, it delivers superior running precision. Its Universal Matchable (SU) design allows two bearings to be paired in a universal arrangement, simplifying mounting and ensuring optimal preload and performance. This bearing is pre-lubricated and capable of handling combined loads, making it an ideal solution for demanding, high-speed machinery.
7030 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7030 | Standard bore diameter (150 mm) and series designation. |
| AC | Angular Contact design with a 25° contact angle. |
| D | Signifies a Universal Matchable (SU) bearing, designed for pairing. |
| P4A | Indicates a high-precision tolerance class, exceeding ABEC 7/ISO P4 standards. |
| DB | Specifies a Back-to-Back (DB) mounting arrangement for the matched set. |
7030 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design with a 25° contact angle and phenolic cage provides high rigidity, enabling the bearing to support significant combined radial and axial loads.
- Precision Performance: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring minimal runout and vibration for ultra-precise applications.
- Optimized for High-Speed Operation: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 11,000 rpm, making it a true high-speed bearing.
- Simplified Installation & Reliability: The Universal Matchable (SU) feature allows for direct pairing without selective mounting, ensuring consistent light preload (Class B) and reliable performance out-of-the-box.
7030 ACD/P4ADGB Bearing Typical Application Areas
The 7030 ACD/P4ADGB is engineered for high-demand sectors, including:
- Machine Tool Spindles (e.g., milling, grinding, and turning centers)
- High-Speed & Precision Spindles for PCB drilling and routing
- Industrial Pumps and Compressors
