71822 CD/HCP4 Bearing Product Overview & Core Advantages
The 71822 CD/HCP4 is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and speed capability. Its defining feature is the combination of a 15° contact angle and P4 (ABEC-7) tolerance class, ensuring minimal runout and superior performance under demanding conditions. The bearing is preloaded and comes pre-lubricated, making it ready for immediate installation in high-speed spindles and precision machinery where high rigidity and low operational vibration are critical.
71822 CD/HCP4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 71822 | Basic bearing designation indicating the metric size series (18) and bore diameter (110 mm). |
| CD | Indicates a high-precision, duplex configuration with a specific contact angle and preload for optimal stiffness. |
| HC | Signifies the use of Hybrid Ceramic balls, combining ceramic balls with steel rings for enhanced speed and life. |
| P4 | Denotes the tolerance class equivalent to ABEC-7, specifying extremely tight dimensional and running accuracy. |
71822 CD/HCP4 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, enabling higher limiting speeds (15,000 rpm).
- Phenolic Resin Cage: The lightweight and robust phenolic cage ensures excellent guidance of the ceramic balls, contributing to smooth operation and high-speed stability with minimal friction.
- High-Precision & Preload: Manufactured to P4 tolerance and supplied with preload, this bearing delivers superior rotational accuracy and system rigidity, minimizing deflection under load.
- Optimized Load Capacity: The 15° contact angle is ideal for applications with combined loads, offering a high radial dynamic load rating of 7178 lbf while effectively handling thrust loads in one direction.
