71922 CD/P4ADGD Bearing Product Overview & Core Advantages
The 71922 CD/P4ADGD is a precision angular contact ball bearing designed for applications demanding exceptional rigidity and accuracy. As a universal matchable (SU) bearing supplied in a preloaded duplex set, it delivers superior performance under combined radial and axial loads. Manufactured to P4A tolerance class with a 15° contact angle and heavy preload (Class D), this bearing is engineered for high-stability applications requiring minimal deflection and maximum operational precision.
71922 CD/P4ADGD Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Duplex bearing arrangement with 15° contact angle in universal match configuration |
| P4A | High precision tolerance class with enhanced running accuracy requirements |
| DGD | Heavy preload (Class D) designation for maximum rigidity and minimal deflection |
71922 CD/P4ADGD Bearing Structural Features & Performance Benefits
Enhanced Rigidity & Load Capacity: The duplex arrangement with heavy preload provides exceptional stiffness, enabling the bearing to handle significant combined loads while maintaining precise shaft positioning. With a radial dynamic load rating of 22,725 lbf and static load rating of 32,175 lbf, it offers reliable performance in demanding applications.
Precision Engineering: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, this bearing ensures minimal runout and vibration. The phenolic cage material provides excellent dimensional stability and reduced friction at high speeds.
Optimized Performance: The 15° contact angle is ideal for applications requiring both radial and axial load capacity. With 28 precision balls of 12.7mm diameter and chrome steel construction, the bearing delivers smooth operation and extended service life.
Universal Matchability: As an SU-type universal matchable bearing, it can be paired in various configurations (back-to-back, face-to-face, or tandem) to meet specific application requirements without additional machining or selection.
