| Suffix | Technical Meaning | Advantage |
|---|---|---|
| CE | Contact Angle (15°) & High Precision | Optimized for combined loads and high-speed operation |
| GA | Light Preload (Class A) | Reduces deflection and improves positional accuracy |
| P4A | High Precision Tolerance Class | Superior running accuracy and dimensional stability |
7007 CEGA/P4A Bearing Structural Features & Performance Benefits
High Precision & Rigidity: The P4A tolerance class ensures minimal runout and vibration, while the 15° contact angle provides optimal stiffness against combined radial and axial loads. The phenolic cage offers excellent dimensional stability at high speeds.
Superior Load Capacity: With a dynamic load rating of 2565 lbf and static load rating of 1474 lbf, this bearing handles significant combined loads while maintaining precision.
High-Speed Performance: The phenolic cage and optimized internal geometry enable a limiting speed of 56,000 rpm, making it suitable for high-speed spindles and precision machinery.
Universal Matching Capability: Designated as Universal Matchable (SU), these bearings can be supplied in sets of 3 for preloaded duplex arrangements, enhancing system rigidity and accuracy.
