S71916 ACD/HCP4A Bearing Product Overview & Core Advantages
The S71916 ACD/HCP4A is a single-row angular contact ball bearing engineered for applications demanding high precision and superior performance. Its defining feature is the ceramic ball material combined with a P4 (ABEC-7) tolerance class, making it an exceptional choice for high-speed operation and high-reliability scenarios. This bearing is preloaded and pre-lubricated, ready to handle significant combined loads with a 25° contact angle, offering high rigidity and operational stability in a compact design.
S71916 ACD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| ACD | Optimized internal geometry with a 25° contact angle. | Provides high rigidity and excellent capability for handling combined radial and axial loads. |
| HC | Hybrid Ceramic (Silicon Nitride balls). | Reduces friction, lowers operating temperature, and enables higher limiting speeds. Offers longer service life and non-conductive properties. |
| P4A | High-Precision Tolerance Class (ABEC-7 / ISO P4). | Ensures extremely tight dimensional and running accuracy for applications requiring minimal vibration and high rotational precision. |
S71916 ACD/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The optimized 25° contact angle and robust construction enable the bearing to support significant combined loads (radial and axial) simultaneously, providing stable and rigid support for shafts.
- Superior High-Speed Performance: The combination of ceramic balls and a lightweight phenolic cage significantly reduces centrifugal forces and friction, allowing for a high limiting speed of 12,000 rpm. This makes it an ideal high-speed bearing.
- Precision and Longevity: Manufactured to P4 precision class with a sealed design, this bearing ensures smooth, quiet, and accurate operation, contributing to extended service life and consistent performance in demanding environments.
- Ready-to-Use Convenience: The bearing comes pre-lubricated and sealed, protecting against contamination and simplifying installation for immediate, maintenance-free operation within its specified temperature range.
