7016 ACEGA/HCP4AL Bearing Product Overview & Core Advantages
The 7016 ACEGA/HCP4AL is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads (radial and axial loads simultaneously), this single bearing features a 25° contact angle for optimal axial load capacity. Manufactured to P4A tolerance class, it delivers superior running accuracy and is universally matchable (SU designation), allowing for precise preload control when mounted in pairs. Its construction with ceramic balls and phenolic cage enables superior high-speed performance up to 28,000 rpm, making it ideal for high-reliability, precision machinery.
7016 ACEGA/HCP4AL Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle. |
| EGA | Specifies a universally matchable (SU) bearing set. "EGA" indicates specific internal geometry and preload (Extra light / Class A) for precise pairing. |
| HC | Hybrid Ceramic: Denotes the use of ceramic balls (typically silicon nitride) for reduced weight, lower friction, and higher speed capability. |
| P4A | Specifies the tolerance class, indicating very high precision levels for both dimensional and running accuracy. |
| L | Indicates the bearing is lubricated from the factory. |
7016 ACEGA/HCP4AL Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces centrifugal forces, lowers operating temperature, and extends service life, especially in high-speed applications.
- Phenolic Resin Cage: This lightweight and robust cage material offers excellent dimensional stability and low friction at high speeds, contributing directly to the bearing's high limiting speed of 28,000 rpm.
- High Rigidity & Load Capacity: The angular contact design and 25° contact angle provide high rigidity and enable the bearing to support significant combined radial and axial loads.
- Ultra-Precision P4A Tolerance: Manufactured to the strictest dimensional and running accuracy standards, ensuring minimal vibration and superior performance in precision spindles.
- Universal Matchability (SU): Allows for precise preload adjustment when mounted in pairs (back-to-back or face-to-face), simplifying assembly and optimizing system stiffness.
