7016 FEGA/P4A Bearing Product Overview & Core Advantages
The 7016 FEGA/P4A is a single row angular contact ball bearing engineered for ultra-high precision applications. Operating under the stringent P4A tolerance class, it is designed to deliver exceptional rotational accuracy and dimensional stability. Its 18° contact angle is optimized to support significant combined loads, effectively managing both radial and axial forces. The bearing features a phenolic resin cage and is pre-lubricated, contributing to its high-speed capabilities and reliable performance in demanding operational environments.
Model Code Breakdown
| Suffix Code | Technical Meaning |
|---|---|
| FE | Identifies a specific optimized internal geometry for enhanced performance. |
| GA | Indicates a specific preload level: Extra light (Class A). |
| P4A | Denotes an ultra-precision tolerance class with tighter running accuracy than ABEC 7. |
7016 FEGA/P4A Bearing Structural Features & Performance Benefits
- Ultra-High Precision & Rigidity: Manufactured to P4A tolerance class with a phenolic resin cage, this bearing ensures minimal runout and high dimensional stability, providing superior rigidity for precise shaft positioning.
- Optimized Load Capacity: The 18° contact angle is engineered to efficiently handle combined radial and axial loads, making it ideal for applications with complex loading conditions.
- High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the optimized internal geometry and pre-lubrication contribute to a high limiting speed of 28,000 rpm.
- Universal Matching Capability (SU): This bearing is universally matchable, allowing multiple bearings to be mounted in sets (up to 4) to achieve specific preload and stiffness requirements without selective sorting.
7016 FEGA/P4A Bearing Typical Application Areas
This precision angular contact bearing is critical in high-performance machinery, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Aerospace & Defense Systems
- Medical & Dental Equipment
