71914 CD/P4ADGB Bearing Product Overview & Core Advantages
The 71914 CD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a pre-lubricated, light preload (Class B) configuration, it is engineered to handle combined radial and axial loads simultaneously. Its P4A tolerance class ensures superior running accuracy, making it an ideal choice for high-speed spindles and other high-precision machinery where reliability and performance are critical.
71914 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Specifies a 15° contact angle and a specific internal design optimized for universal matching. |
| P4A | Indicates a high-precision tolerance class with enhanced dimensional and running accuracy requirements. |
| DGB | Denotes a universal matchable (SU) bearing pair, pre-set with light preload (Class B) for immediate installation and optimal performance. |
71914 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design with a 15° contact angle provides excellent resistance to combined loads, ensuring stable operation under demanding conditions. The phenolic cage contributes to smooth operation at high speeds.
- Precision Performance: Manufactured to P4A tolerance standards, this bearing guarantees minimal runout and vibration, which is crucial for applications requiring extreme positional accuracy.
- Universal Matchability (SU): As a universal matchable bearing, it can be paired in any combination (back-to-back, face-to-face, or tandem) without pre-selection, simplifying inventory and assembly processes. The supplied set is pre-configured with a light preload to eliminate axial play and enhance system stiffness.
- Optimized for High-Speed Operation: The combination of a lightweight phenolic cage, precision-ground chrome steel components, and a limiting speed of 24,000 rpm makes it suitable for high-speed spindle applications.
71914 CD/P4ADGB Bearing Typical Application Areas
This high-precision bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Rotary Tables: Indexing and positioning systems.
- High-Frequency Motors and Spindles: Where minimal runout and high rotational accuracy are mandatory.
- Medical and Dental Equipment: High-speed handpieces and scanners.
- Aerospace and Defense Systems: Gyroscopes, radar systems, and other precision instrumentation.
