7226 ACD/P4ADGB Bearing Product Overview & Core Advantages
The 7226 ACD/P4ADGB is a precision angular contact ball bearing designed for demanding applications requiring high rotational accuracy and rigidity. Engineered to a P4A tolerance class, it excels in high-speed performance and can accommodate combined radial and axial loads simultaneously. Its universal matchable (SU) design allows for flexible mounting in preloaded sets, providing exceptional operational stability and system rigidity in high-precision machinery.
7226 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| ACD | 25° Contact Angle | Optimized for carrying significant axial loads in addition to radial loads. |
| P4A | High Precision Tolerance Class | Guarantees extremely tight dimensional and running accuracy for superior performance. |
| DGB | Universal Matchable (SU), Light Preload (Class B) | Bearings are supplied as a matched set of 2 for simplified installation and optimal preload configuration. |
7226 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design with a 25° contact angle and double-row configuration provides high rigidity, enabling the bearing to handle substantial combined loads effectively.
- Superior High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, contributing to a high limiting speed of 7,500 rpm. The open design and pre-lubrication facilitate efficient heat dissipation.
- Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls on the bore diameter (130 mm), outside diameter (230 mm), and width (80 mm), ensuring smooth, quiet, and vibration-free operation.
- Matched Set Simplicity: The Universal Matchable (SU) designation means the supplied pair is pre-configured for immediate installation, eliminating complex calculations and ensuring consistent, high-performance bearing arrangement.
7226 ACD/P4ADGB Bearing Typical Application Areas
This bearing is ideally suited for high-precision, high-speed applications, including:
- Machine Tool Spindles
- Precision Grinding Spindles
- High-Frequency Motors
