7014 CD/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7014 | Standard bearing series designation indicating a 70mm bore, 110mm OD, and 40mm width. |
| C | Specifies a 15° contact angle, optimized for high-speed operation and high axial load capacity. |
| D | Indicates the bearing is supplied as a duplex pair in a specific arrangement. |
| P4A | Denotes a high precision tolerance class with enhanced running accuracy for demanding applications. |
| DT | Signifies the Duplex Tandem arrangement, where two bearings are mounted to increase axial load capacity in one direction. |
7014 CD/P4ADT Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex tandem (DT) arrangement creates an exceptionally rigid bearing system, capable of supporting high combined radial and axial loads. This configuration significantly enhances axial stiffness and load-carrying capacity in a single direction.
Precision Performance: Manufactured to P4A tolerance class standards, this bearing ensures minimal runout and vibration, which is crucial for applications requiring high rotational accuracy.
High-Speed Capability: The 15° contact angle and phenolic resin cage contribute to excellent high-speed performance, with a limiting speed of 22,000 rpm. The lightweight cage reduces centrifugal forces, enabling smoother operation at high rotational velocities.
Preloaded & Matched Set: Supplied as a preloaded and matched pair, these bearings are ready for installation without requiring additional adjustment, ensuring optimal performance and simplifying the assembly process.
7014 CD/P4ADT Bearing Typical Application Areas
The 7014 CD/P4ADT is ideally suited for high-performance applications, including:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Rotary Tables
- High-Frequency Motors
