71813 ACD/HCP4 Bearing Product Overview & Core Advantages
The 71813 ACD/HCP4 is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Designed to accommodate primarily axial loads in one direction and combined loads, this bearing features ceramic balls and P4 (ABEC-7) precision tolerance for superior performance in demanding environments. Its compact design with a 10mm width makes it ideal for space-constrained applications where high-speed capability and thermal stability are critical.
71813 ACD/HCP4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| ACD | 25° Contact Angle Design | Optimized for high axial load capacity and rigid support |
| HC | Hybrid Ceramic (Silicon Nitride Balls) | Reduced friction, higher speed capability, and electrical insulation |
| P4 | ABEC-7 Precision Tolerance Class | Ultra-precise running accuracy for critical applications |
71813 ACD/HCP4 Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces friction, enables higher limiting speeds (24,000 rpm), and provides electrical insulation properties. This construction also offers superior thermal stability across the operating temperature range (-30° to 110°C).
Precision Engineering: Manufactured to P4 tolerance class with optimized contact angle of 25°, this bearing delivers exceptional running accuracy and minimizes vibration. The phenolic resin cage ensures smooth operation at high speeds while reducing weight.
Load Capacity & Rigidity: With a radial dynamic load rating of 2858 lbf and static load rating of 3150 lbf, this bearing provides reliable performance under significant combined loads. The angular contact design offers high axial rigidity for precise positioning applications.
Pre-lubricated Design: Factory-applied lubrication ensures immediate operation and consistent performance, reducing maintenance requirements during the bearing's service life.
