| Code Segment | Technical Meaning |
|---|---|
| 7016 | Standard bearing series number (80mm bore, 125mm OD, 44mm width) |
| ACE | 25° contact angle, universal matchable design |
| HC | Hybrid ceramic balls (ceramic balls with steel rings) |
| P4A | High precision tolerance class (superior to ABEC 7) |
| DGA | Preloaded pair (2 bearings), extra light preload |
7016 ACE/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides superior rigidity and can sustain significant combined loads from any direction. With a 25° contact angle, it offers excellent axial load capacity in both directions.
Enhanced High-Speed Performance: The phenolic cage and hybrid ceramic balls significantly reduce centrifugal forces and friction, enabling a limiting speed of 28,000 rpm. The lower density of ceramic balls minimizes skidding at ultra-high speeds.
Precision & Longevity: Manufactured to P4A tolerance class with precise bearing dimensions (bore: 80mm, OD: 125mm, width: 44mm), this bearing ensures minimal runout and vibration. The universal matchable (SU) feature allows for flexible mounting arrangements without performance degradation.
Optimized for Precision Applications: The extra light preload (Class A) minimizes friction while maintaining shaft positioning accuracy, crucial for high-precision spindle applications.
