Engineered with a 15° contact angle and manufactured to P4A super-precision tolerance, this bearing excels at handling combined radial and axial loads simultaneously. Its compact design, featuring a ceramic ball and phenolic cage, enables superior high-speed capability up to 28,000 rpm and provides excellent rigidity for stable operation in precision machinery.
S71916 CEGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Advantage |
|---|---|---|
| CEGA | Enhanced internal design with optimized contact geometry and preload | Improved running accuracy and stiffness characteristics |
| HC | Hybrid Ceramic construction (steel rings with ceramic balls) | Reduced friction, higher speed capability, and longer service life |
| P4A | Super precision tolerance class | Exceptional running accuracy and minimal vibration for precision applications |
S71916 CEGA/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The combination of chrome steel rings and silicon nitride ceramic balls significantly reduces friction, heat generation, and wear, enabling higher operating speeds and extended bearing life.
Precision Phenolic Cage: The phenolic resin cage provides excellent dimensional stability at high speeds, reduced weight for lower centrifugal forces, and superior lubrication retention compared to metal cages.
Optimized Internal Geometry: With a 15° contact angle and precision-ground raceways, this bearing delivers optimal performance under combined loading conditions while maintaining high running accuracy.
Super-Precision Manufacturing: Manufactured to P4A tolerance class with tight dimensional controls (bore: -0.004mm to 0, OD: -0.004mm to 0), ensuring minimal runout and vibration for critical applications.
