7052 ACD/P4ADGB Bearing Product Overview & Core Advantages
The 7052 ACD/P4ADGB is a precision double row angular contact ball bearing designed for applications requiring exceptional rotational accuracy and high rigidity. Engineered to accommodate combined loads (radial and bidirectional axial loads) simultaneously, this bearing features a universal matchable (SU) design that simplifies mounting and ensures optimal preload when paired. Its P4A tolerance class guarantees superior dimensional and running accuracy, making it ideal for high-speed, high-precision machinery where reliability is paramount.
7052 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | 25° contact angle, optimized for high axial load capacity and rigidity. |
| P4A | High precision tolerance class exceeding ABEC 7, ensuring minimal runout and vibration. |
| DGB | Universal Matchable (SU) bearing set. Two bearings are supplied as a matched pair for simplified installation and consistent preload. |
7052 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and 25° contact angle provide superior stiffness, enabling the bearing to handle significant combined radial and axial loads with minimal deflection.
- Precision & High-Speed Performance: The P4A tolerance class and phenolic resin cage contribute to smooth operation and low vibration at high rotational speeds, with a limiting speed of 4,500 rpm.
- Optimized for Matched Sets: As a Universal Matchable (SU) bearing supplied in a set of two, it ensures ease of assembly and maintains a consistent light preload (Class B) for enhanced system performance.
- Durable Construction: Manufactured from chrome steel for both rings and balls, this bearing offers high fatigue resistance and long service life in demanding environments.
