S7016 ACEGA/P4A Bearing Product Overview & Core Advantages
The S7016 ACEGA/P4A is a precision angular contact ball bearing designed for high-performance applications. Engineered to an extra light preload (Class A) and P4A super-precision tolerance, it delivers exceptional rotational accuracy and system rigidity. Its 25° contact angle and sealed design enable it to handle combined radial and axial loads simultaneously, making it ideal for demanding, high-speed machinery requiring long-term reliability and minimal maintenance.
S7016 ACEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| AC | Angular Contact | Optimized for combined loads. |
| EGA | Sealed (Contact Seal) | Provides effective protection against contaminants. |
| P4A | Super Precision Tolerance | Guarantees extremely tight running accuracy for high-speed applications. |
S7016 ACEGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single bearing design with P4A tolerance class and extra light preload (Class A) ensures superior system stiffness and minimal runout, critical for precision spindles.
- Superior Load Capacity: The 25° contact angle is engineered to efficiently support significant combined radial and axial loads.
- Optimized High-Speed Performance: The phenolic cage and precision-ground chrome steel components contribute to smooth operation and a high limiting speed of 28,000 rpm.
- Long-Term Reliability & Low Maintenance: The integrated seals (EGA) and factory-applied grease lubrication protect the bearing from contamination and provide a long service life within a wide temperature range of -30°C to 110°C.
