71816 ACD/P4 Bearing Product Overview & Core Advantages
The 71816 ACD/P4 is a single-row angular contact ball bearing designed for applications demanding high precision and superior rigidity. Engineered to a P4 (ABEC-7) tolerance class, it excels in handling combined loads, particularly high axial loads in one direction, thanks to its optimized 25° contact angle. Its compact design, featuring a 10 mm width, makes it an ideal solution for space-constrained, high-performance machinery requiring exceptional running accuracy and reliability.
71816 ACD/P4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Indicates a 25° contact angle and that the bearing is designed for optimized axial load capacity and high-speed operation. |
| P4 | Denotes a high precision tolerance class equivalent to ABEC-7, ensuring minimal runout and superior dimensional stability. |
71816 ACD/P4 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The optimized 25° contact angle and robust construction enable the bearing to support significant combined radial and axial loads simultaneously, providing exceptional operational stability.
- High-Speed Performance: The lightweight phenolic resin cage ensures excellent dimensional stability and low friction, contributing to a high limiting speed of 17,000 rpm.
- Precision Engineering: Manufactured to P4 precision class with tight dimensional tolerances on the bore diameter, outside diameter, and width, guaranteeing smooth, quiet, and vibration-free operation.
- Durable Construction: Made from high-grade chrome steel for both rings and balls, the bearing offers high fatigue resistance and long service life.
