7014 CD/P4ADBB Bearing Product Overview & Core Advantages
The 7014 CD/P4ADBB is a precision duplex angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This metric bearing features a back-to-back (DB) matched arrangement and a P4A tolerance class, making it ideal for high-precision spindles and machinery. Its key advantage lies in its ability to handle combined loads (radial and axial) simultaneously while providing high system rigidity and stable operation at high speeds.
7014 CD/P4ADBB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7014 | Basic bearing series, indicating a 70mm bore, 110mm OD, and 40mm width. |
| C | 15° contact angle, optimized for carrying axial loads. |
| D | Indicates a duplex bearing (two bearings supplied as a set). |
| P4A | High-precision tolerance class with enhanced dimensional and running accuracy. |
| DB | Back-to-Back arrangement, providing high moment rigidity and excellent stability. |
| B | Light preload (Class B), reducing axial and radial play for precise shaft positioning. |
7014 CD/P4ADBB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex back-to-back (DB) configuration creates a wide effective spread, significantly increasing the bearing's resistance to moment loads and providing superior system rigidity. This design enables it to support substantial combined radial and axial loads.
- Precision Performance: Manufactured to P4A tolerance class with a 15° contact angle, this bearing ensures minimal runout and smooth, precise rotation, which is critical for high-speed applications.
- Optimized High-Speed Operation: The lightweight phenolic cage minimizes centrifugal forces, contributing to a high limiting speed of 22,000 rpm. The bearings are pre-lubricated for immediate operation.
- Durable Construction: Both rings and balls are made from high-grade chrome steel, offering excellent wear resistance and long service life under demanding conditions.
