7014 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7014 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-set pair, it is engineered to accommodate combined loads (radial and axial) simultaneously. Its P4A tolerance class ensures ultra-precise dimensions and running accuracy, making it ideal for high-speed spindles and other high-precision machinery. The light preload (Class B) minimizes deflection under operational loads, contributing to superior system stiffness and positioning accuracy.
Model Code Breakdown
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 7014 | Basic Bearing Series | Standard metric size designation (70mm bore, 110mm OD, 40mm width). |
| CD | Contact Angle & Design | Specifies a 15° contact angle and optimized internal design for high rigidity. |
| P4A | Tolerance Class | Denotes a high-precision grade with extremely tight dimensional and running tolerances. |
| DGB | Universal Matchable Pair | Indicates the bearing is supplied as a universally matchable pair (SU), allowing flexible arrangement (DB, DF, DT) to handle various load conditions. |
7014 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design with a 15° contact angle and the use of a matched pair arrangement provide high system rigidity, enabling the bearing to support significant combined radial and axial loads.
- Precision Performance: Manufactured to P4A tolerance class, this bearing guarantees minimal runout and vibration, which is critical for applications requiring high rotational accuracy.
- Optimized High-Speed Operation: The lightweight and robust phenolic cage ensures stable operation and reduced centrifugal forces, contributing to a high limiting speed of 22,000 rpm. The open design allows for efficient lubrication management.
- Superior Material Construction: Made from chrome steel for both rings and balls, the bearing offers high fatigue life and durability under demanding operating conditions.
