7200 ACD/P4ADGB Bearing Product Overview & Core Advantages
The 7200 ACD/P4ADGB is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Featuring a 25° contact angle and Universal Matchable (SU) design, this bearing excels at handling combined loads—simultaneously supporting significant radial and axial forces. Manufactured to P4A tolerance class, it delivers superior running accuracy, making it ideal for high-speed spindles and other precision machinery where minimal runout and high reliability are critical.
7200 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle, optimized for combined loads. |
| P4A | High precision tolerance class, providing extremely tight dimensional and running accuracy. |
| DGB | Universal Matchable (SU) bearing set. Two bearings are supplied as a universally matchable pair with a light preload (Class B). |
7200 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and phenolic cage provide excellent stability, enabling the bearing to handle high combined radial and axial loads with minimal deflection.
