7019 CEGA/P4A Bearing Product Overview & Core Advantages
The 7019 CEGA/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. As a single bearing with P4A super precision tolerance, it delivers superior running accuracy and dimensional stability. Its 15° contact angle and Universal Matchable (SU) design enable optimal performance under combined radial and axial loads. The bearing comes prelubricated and features an open design with a phenolic cage, making it ideal for high-speed operation up to 15,000 rpm while maintaining extra light preload (Class A) for minimal friction and heat generation.

| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| CE | Enhanced internal design with optimized contact conditions | Improved load distribution and high rigidity |
| GA | Matched bearing set with specific axial clearance | Precision universal matching for optimal preload |
| P4A | Super precision tolerance class | Exceptional running accuracy and dimensional stability |
7019 CEGA/P4A Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring exceptional dimensional accuracy and consistent performance in precision applications.
High-Speed Capability: The phenolic resin cage provides excellent strength-to-weight ratio, enabling stable operation at limiting speeds of 15,000 rpm while reducing centrifugal forces and friction.
Superior Load Capacity: With a dynamic load rating of 9,945 lbf and static load rating of 8,550 lbf, the bearing efficiently handles combined radial and axial loads thanks to its optimized 15° contact angle.
Universal Matching Design: As part of a matched set of 2 bearings with SU designation, it enables precise axial preload control and simplified mounting in back-to-back or face-to-face arrangements.
