7020 FEGA/P4A Bearing Product Overview & Core Advantages
The 7020 FEGA/P4A is a single-row angular contact ball bearing engineered for applications demanding exceptional precision and rigidity. Positioned in the ultra-precision P4A tolerance class, it delivers superior running accuracy and dimensional stability. Its core advantage lies in its ability to support high combined loads (radial and axial) simultaneously, making it ideal for high-speed spindles and precision machinery. The bearing features a Universal Matchable (SU) designation, allowing for precise preload control when mounted in sets, and is pre-lubricated for immediate operation.
7020 FEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| FE | Steel machined window-type cage, pressed |
| GA | Light preload (Class A) |
| P4A | Ultra-precision tolerance class, tighter than ABEC 7/ISO P4 |
7020 FEGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: Manufactured to P4A tolerance class with extremely tight dimensional control (bore/OD tolerance: -0.004mm to 0), ensuring minimal runout and superior positional accuracy for demanding applications.
- Optimized Load Capacity: The 18° contact angle is optimized to handle significant combined radial and axial loads efficiently, with a dynamic load rating of 9945 lbf and static load rating of 8775 lbf.
- High-Speed Capability: The combination of a lightweight, robust phenolic cage, precision-ground chrome steel components, and optimized internal geometry enables a high limiting speed of 15,000 rpm.
- Universal Matching & Preload: Designated as Universal Matchable (SU), these bearings can be supplied in sets of up to 4 bearings with selective assembly to achieve precise preload (in this case, Extra Light / Class A), maximizing system stiffness and performance.
7020 FEGA/P4A Bearing Typical Application Areas
This high-precision angular contact bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy positioning systems.
- Medical Equipment: Dental handpieces, centrifuges, and imaging devices.
- Aerospace & Defense Systems: Gyroscopes, radar equipment, and navigation systems.
