7014 FEGA/HCPA9A Bearing Product Overview & Core Advantages
The 7014 FEGA/HCPA9A is a precision angular contact ball bearing engineered for exceptional performance in demanding applications. This single bearing features an Extra Light (Class A) preload and is manufactured to the stringent PA9A tolerance class, ensuring high running accuracy and minimal vibration. Its design is optimized to handle combined loads, providing reliable support for complex force scenarios. The use of ceramic balls and a phenolic cage contributes to its capabilities as a high-speed bearing, offering extended service life and consistent operation.
7014 FEGA/HCPA9A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 7014 | Basic Series & Size | Denotes a metric series bearing with a 70mm bore, 110mm OD, and 20mm width. |
| FE | Preload Class | Indicates an Extra Light (Class A) preload, minimizing friction and heat generation for high-speed operation. |
| GA | Universal Matching | Signifies the bearing is Universal Matchable (SU), allowing for precise pairing in sets of two to achieve specific preload or rigidity. |
| /HCPA9A | Tolerance & Internal Design | Specifies the PA9A tolerance class, representing the highest level of dimensional and running accuracy for precision applications. |
7014 FEGA/HCPA9A Bearing Structural Features & Performance Benefits
High-Speed & Rigidity: The combination of a phenolic resin cage and ceramic (Si3N4) balls significantly reduces centrifugal forces and inertial mass, enabling stable operation at the high limiting speed of 28,000 rpm. The defined 18° contact angle and extra light preload provide excellent axial rigidity while maintaining low running torque.
Superior Load Capacity: Engineered with a high ball count (25 balls) and precision-ground raceways, this bearing delivers a high dynamic load rating of 5,265 lbf and a static load rating of 4,118 lbf, making it robust against combined radial and axial loads.
Precision & Thermal Stability: Manufactured to PA9A tolerances with tight dimensional control on the bore, OD, and width. The phenolic cage offers superior dimensional stability and low heat conductivity, contributing to consistent performance across the specified temperature range of -30°C to 110°C.
7014 FEGA/HCPA9A Bearing Typical Application Areas
