S7007 FE/P4ADGA Bearing Product Overview & Core Advantages
The S7007 FE/P4ADGA is a super-precision double row angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. Positioned in the P4A tolerance class, it delivers ultra-precise running characteristics. Its double row design enables it to support combined loads—simultaneously handling substantial radial loads and bidirectional axial loads. This makes it an ideal, compact solution for high-speed spindles and other high-reliability machinery where space is at a premium and performance is critical.
S7007 FE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| FE | Indicates a non-contact sealing solution, typically a low-friction, non-rubbing seal designed to protect against contamination while minimizing heat generation. |
| P4A | Denotes a super-precision tolerance class with enhanced running accuracy and dimensional stability beyond standard P4 levels. |
| DGA | Specifies a universal matchable (SU) bearing design with an Extra light (Class A) preload. This allows two bearings to be mounted in any configuration (face-to-face, back-to-back, or tandem) without pre-set axial clearance, simplifying assembly and ensuring optimal performance. |
S7007 FE/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact structure, combined with a generous ball quantity (17) and a 18° contact angle, provides superior stiffness and the ability to handle significant combined radial and axial loads from both directions.
- Super-Precision & High-Speed Performance: Manufactured to P4A tolerance standards with a phenolic resin cage (TN9 style), this bearing ensures minimal vibration and stable operation at high rotational speeds, with a limiting speed of 56,000 rpm.
- Optimized for Longevity & Reliability: The FE non-contact seal effectively excludes contaminants while the bearing is pre-lubricated with high-performance grease, offering a wide operating temperature range (-30°C to 110°C) and contributing to a long, maintenance-free service life.
- Universal Matching Design: The Universal Matchable (SU) feature with extra light preload provides design flexibility, allowing for precise axial positioning and simplified installation in complex spindle arrangements.
S7007 FE/P4ADGA Bearing Typical Application Areas
This bearing is specifically designed for high-performance machinery, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling and routing machines.
- High-Frequency Motors: Spindles for robotics and automation.
- Medical Equipment: High-speed dental handpieces and imaging devices.
