| Code Segment | Technical Meaning |
|---|---|
| 7014 | Standard bore diameter (70 mm) and series designation. |
| AC | Angular Contact design with a 25° contact angle. |
| EGA | Universal Matchable (SU) bearing supplied in a set of 3 for precise preload arrangement. |
| HC | Hybrid Ceramic construction, featuring ceramic balls for reduced friction and higher speed capability. |
| P4A | Super Precision tolerance class, exceeding ABEC 7 standards for exceptional running accuracy. |
7014 ACEGA/HCP4A Bearing Structural Features & Performance Benefits
High-Speed Performance: The combination of ceramic balls and a lightweight phenolic cage significantly reduces centrifugal forces, enabling a high limiting speed of 29,000 rpm. This makes it suitable for ultra-high-speed spindles.
Rigidity and Load Capacity: The 25° contact angle and extra light preload provide high system rigidity, allowing the bearing to effectively support combined radial and axial loads (Dynamic: 5062 lbf, Static: 3892 lbf).
Thermal and Dimensional Stability: Manufactured to P4A precision tolerances with a narrow bore and OD tolerance band, this bearing ensures minimal runout and consistent performance under varying thermal conditions (operating range: -30°C to 110°C).
Optimized for Matched Sets: As a Universal Matchable (SU) bearing supplied in a set of 3, it allows for simplified assembly of preloaded duplex or triplex arrangements, maximizing stiffness and accuracy in the final application.
