71906 CDGC/P4A Bearing Product Overview & Core Advantages
The 71906 CDGC/P4A is a single row angular contact ball bearing designed for applications demanding high precision and superior running accuracy. Manufactured to the stringent P4A tolerance class, this bearing is engineered to accommodate high speeds and combined loads, making it ideal for high-performance machinery. Its universal matchable (SU) design allows for flexible mounting in various preload configurations, while the phenolic cage ensures reliable operation at high rotational speeds.
71906 CDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 71906 | Basic bearing designation, indicating the size series and bore diameter (30 mm). |
| C | Specifies a 15° contact angle, optimized for handling high axial loads in one direction. |
| DG | Indicates a Moderate / Class C preload, providing enhanced rigidity and reduced deflection for precise applications. |
| P4A | Denotes the tolerance class, signifying very high precision in dimensions and running accuracy. |
71906 CDGC/P4A Bearing Structural Features & Performance Benefits
The performance of the 71906 CDGC/P4A is driven by its specific construction:
- High Precision & Rigidity: Built to P4A tolerance class with a moderate preload (C), this bearing delivers exceptional dimensional stability and minimizes operational deflection under load, ensuring precise shaft positioning.
- Optimized Load Capacity: The 15° contact angle is engineered to efficiently support significant axial loads in one direction while also handling radial loads, making it suitable for combined load conditions.
- Superior High-Speed Performance: The lightweight and robust phenolic cage is critical for maintaining bearing integrity and smooth operation at the high limiting speed of 100,500 rpm, reducing centrifugal forces and friction.
- Universal Matching Capability (SU): As a universal matchable bearing, it can be paired with another identical bearing in various arrangements (back-to-back, face-to-face, or tandem) to create a matched set that meets specific application requirements for preload and stiffness.
71906 CDGC/P4A Bearing Typical Application Areas
The 71906 CDGC/P4A is ideally suited for high-precision and high-speed machinery, including:
- Machine Tool Spindles
