7214 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7214 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. As a universal matchable (SU) bearing supplied in a pre-loaded duplex set, it delivers superior rigidity and can accommodate combined radial and axial loads simultaneously. Manufactured to the stringent P4A tolerance class and featuring a phenolic cage, this bearing is engineered for high reliability in precision machinery and high-rotation environments.
7214 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Indicates a duplex bearing set with a 15° contact angle in a universal matchable (SU) arrangement, allowing for flexible mounting configurations to handle combined loads. |
| P4A | Denotes an ultra-high precision tolerance class with enhanced running accuracy, ensuring minimal vibration and superior performance in demanding applications. |
| DGA | Specifies the Extra light (Class A) preload and that the bearing is lubricated from the factory, ready for immediate use. |
7214 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex set configuration and 15° contact angle provide exceptional stiffness, enabling the bearing to support significant combined radial and axial loads with high stability.
- High-Speed Performance: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 28,000 rpm, making it suitable for high-rotation spindles.
- Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional control on the bore diameter, outside diameter, and width, ensuring consistent, high-accuracy operation.
- Universal Matchability: The SU designation means bearings can be mounted in various arrangements (back-to-back, face-to-face, or tandem) to optimize performance for specific load and rigidity requirements.
7214 CD/P4ADGA Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications including:
- Machine Tool Spindles
- High-Speed Grinding & Milling Heads
