71922 CD/P4ADGA Bearing Product Overview & Core Advantages
The 71922 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Operating under the P4A tolerance class, this bearing delivers superior running precision. A key feature is its Universal Matchable (SU) design, allowing two bearings to be universally paired in a back-to-back (DB) or face-to-face (DF) arrangement without selective mounting, simplifying installation and ensuring optimal preload and stiffness. Its extra light preload (Class A) minimizes friction and heat generation, making it ideal for high-speed operation up to 16,250 rpm. This bearing is engineered to handle combined loads, efficiently supporting significant radial loads and axial loads in one direction.

|---|---|
| CD | A 15° contact angle and optimized internal geometry for high-speed performance and radial load capacity. |
| P4A | Indicates a high-precision tolerance class with enhanced dimensional and running accuracy, exceeding ABEC 7 standards. |
| DGA | Signifies a Universal Matchable (SU) bearing pair with an extra light preload (Class A). |
71922 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The angular contact design and P4A tolerance class provide superior rotational accuracy and system stiffness, critical for maintaining positional integrity under load.
- Optimized Load Capacity: With a 15° contact angle, this bearing is engineered to handle high combined radial and axial loads. The dynamic load rating of 22,725 lbf and static load rating of 32,175 lbf ensure reliable performance in demanding conditions.
- Superior High-Speed Performance: The phenolic resin cage offers low weight and excellent acceleration characteristics, contributing to the high limiting speed of 16,250 rpm. The open design facilitates efficient lubrication management.
- Universal Matchability (SU): This feature allows for simplified and precise mounting of bearing pairs, ensuring consistent preload and performance without the need for selective assembly, reducing installation time and complexity.
- Premium Materials: Constructed from chrome steel for both rings and balls, the bearing ensures high durability, wear resistance, and a long operational lifespan.
