7014 CE/P4ADGA Bearing Product Overview & Core Advantages
The 7014 CE/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. Manufactured to P4A tolerance class, this bearing offers superior dimensional and running accuracy. Its universal matchable (SU) design allows for flexible mounting in various preload configurations, while the extra light preload (Class A) ensures low starting and running torque, making it ideal for high-precision spindles and other critical machinery where minimal friction and high rigidity are paramount.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7014 | Basic bearing series and size designation (70mm Bore, 110mm OD, 40mm Width). |
| C | Specifies a 15° contact angle, optimized for high-speed operation and combined loads. |
| E | Indicates an Optimized Internal Design for enhanced performance and load capacity. |
| P4A | Denotes a high precision tolerance class with very tight dimensional and running accuracy limits. |
| DGA | Signifies a Universal Matchable (SU) bearing pair, pre-set for specific axial play or preload when mounted face-to-face or back-to-back. |
7014 CE/P4ADGA Bearing Structural Features & Performance Benefits
High-Speed Capability: The combination of a 15° contact angle and a lightweight phenolic resin cage minimizes centrifugal forces and friction, enabling a high limiting speed of 22,000 rpm. The open design facilitates efficient lubrication and heat dissipation.
High Rigidity and Precision: Manufactured to P4A super-precision standards with extremely tight tolerances on all dimensions, this bearing ensures minimal runout and vibration. This results in superior system rigidity and positional accuracy.
Superior Load Capacity: The angular contact design efficiently supports combined radial and axial loads simultaneously. With a dynamic load rating of 8775 lbf and a static load rating of 8212 lbf, it offers reliable performance under demanding conditions.
Universal Matching (SU): The DGA suffix confirms the bearing is supplied as one of a universally matchable pair. This allows for simplified assembly and the achievement of a defined preload or clearance without selective mounting, ensuring consistent performance.
