| Suffix Code | Technical Meaning | Performance Advantage |
|---|---|---|
| FE | Preloaded Duplex Tandem Arrangement | Provides high system rigidity and precise axial positioning |
| HC | Hybrid Ceramic (Silicon Nitride Balls) | Enables higher speeds, reduced friction, and longer service life |
| P4A | Super Precision Tolerance Class | Ensures exceptional running accuracy and minimal vibration |
S7007 FE/HCP4ADT Bearing Structural Features & Performance Benefits
- Enhanced Rigidity & Load Capacity: The duplex tandem arrangement with preload creates a highly rigid bearing system capable of handling significant combined loads and thrust loads in one direction, ensuring stable performance under demanding conditions.
- Superior High-Speed Capability: The lightweight phenolic resin cage and low-density ceramic balls reduce centrifugal forces, enabling a high limiting speed of 56,000 rpm. This design minimizes friction and heat generation.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control on the bore diameter (35 mm), outside diameter (62 mm), and width (28 mm), guaranteeing consistent high-precision performance.
- Optimized Lubrication & Sealing: Pre-greased for immediate operation and featuring integrated sealing, the bearing is ready for installation and offers reliable performance across its specified temperature range.
