71800 CD/P4 Bearing Product Overview & Core Advantages
The 71800 CD/P4 is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing with a 15° contact angle, it is optimized to support combined loads, handling significant thrust loads in one direction alongside radial loads. Manufactured to the exacting P4 (ABEC-7) tolerance class, it ensures minimal runout and vibration, making it ideal for high-speed spindles and other precision machinery. Its compact design, with a 10 mm bore and 5 mm width, allows for space-saving integration in sophisticated assemblies.
71800 CD/P4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 71800 | The basic series designation for this metric, single-row angular contact ball bearing. |
| C | Indicates a 15° contact angle, providing an optimal balance between radial and axial load capacity. |
| D | Signifies that the bearing is manufactured with a high-precision, phenolic resin cage for reduced friction and high-speed capability. |
| P4 | Denotes the tolerance class, equivalent to ABEC-7. This guarantees extremely tight dimensional and running accuracy. |
71800 CD/P4 Bearing Structural Features & Performance Benefits
- High-Speed Performance: The lightweight and robust phenolic cage (D) minimizes centrifugal forces and ensures stable operation at the high limiting speed of 120,000 rpm.
- Superior Rigidity and Load Capacity: The 15° contact angle (C) and high-grade chrome steel construction enable the bearing to handle substantial combined loads, with a dynamic load rating of 428 lbf and a static load rating of 220 lbf.
- Precision Engineering: The P4 tolerance class ensures ultra-precise bearing dimensions and geometry, resulting in smooth, quiet running and extended service life in demanding applications.
- Optimized for Preload: The design is suitable for preload applications, which increases system stiffness, eliminates axial play, and enhances positional accuracy.
