S7007 FEGA/HCP4A Bearing Product Overview & Core Advantages
The S7007 FEGA/HCP4A is a high-precision, double-row angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and rigidity. This sealed bearing is designed to accommodate combined loads (radial and bidirectional axial loads) simultaneously, making it an ideal solution for compact, high-performance systems. Its P4A super-precision tolerance and ceramic ball construction contribute to superior running accuracy, low heat generation, and extended service life, even at high rotational speeds.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S7007 | Series designation for a 35mm bore, double-row angular contact ball bearing. |
| FE | Designates a universally matchable (SU) bearing, allowing for precise preload setting when mounted in pairs. |
| GA | Indicates an Extra Light (Class A) preload grade. |
| HC | Signifies the use of hybrid ceramic balls (Silicon Nitride), offering benefits like higher speed capability and electrical insulation. |
| P4A | Denotes a super-precision tolerance class, exceeding ABEC 7/ISO P4 standards for exceptional running accuracy. |
S7007 FEGA/HCP4A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double-row design provides significantly higher radial and moment load stiffness compared to single-row bearings, ensuring stable shaft support under combined loads.
Superior High-Speed Performance: The combination of a lightweight phenolic resin cage and low-friction ceramic balls reduces centrifugal forces and operating temperatures, enabling a high limiting speed of 56,000 rpm.
Enhanced Durability & Longevity: The integral seals protect the bearing from contamination, while the factory-applied grease lubrication is suitable for a wide temperature range (-30°C to 110°C), ensuring long-term, maintenance-free operation.
Precision Engineering: Manufactured to P4A tolerance with a consistent 18° contact angle, this bearing delivers ultra-precise rotational performance essential for high-accuracy applications.
