7007 FE/P4ADGA Bearing Product Overview & Core Advantages
The 7007 FE/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 delivers superior dimensional and running accuracy. Its universal matchable (SU) design allows for flexible mounting in various configurations, such as back-to-back or face-to-face, to optimize system rigidity. The bearing is pre-lubricated for immediate use and features an Extra light (Class A) preload, making it ideal for high-precision spindles and other machinery where minimal deflection and high-speed capability are critical.

|---|---|
| 7007 | Basic bearing series designation, indicating a 35mm bore, 62mm OD, and 28mm width. |
| FE | Indicates a phenolic (Polyamide) cage, which is lightweight and suitable for high-speed operation. |
| P4A | Denotes a high-precision tolerance class with enhanced running accuracy requirements. |
| DGA | Specifies the Universal Matchable (SU) arrangement and Extra light preload (Class A). |
7007 FE/P4ADGA Bearing Structural Features & Performance Benefits
- High-Speed Capability: The lightweight phenolic cage (FE) and optimized internal geometry, including a 18° contact angle, enable a high limiting speed of 56,000 rpm, reducing centrifugal forces and heat generation.
- Exceptional Rigidity and Accuracy: Manufactured to P4A precision standards with tight dimensional tolerances, this bearing provides stable, high-rigidity support for spindles, minimizing runout and vibration.
- Universal Matching Design: As a Universal Matchable (SU) bearing, it can be paired with another identical bearing in various arrangements to create a pre-loaded set, simplifying inventory and assembly while achieving the desired system stiffness.
- Optimized Load Capacity: With a dynamic load rating of 4185 lbf and static load rating of 2970 lbf, it reliably handles combined radial and axial loads in high-performance applications.
- Ready-to-Use Lubrication: The bearing comes pre-lubricated, ensuring immediate operation and protection during the initial run-in period within its specified temperature range of -30°C to 110°C.
7007 FE/P4ADGA Bearing Typical Application Areas
