71801 CDGB/P4 Bearing Product Overview & Core Advantages
The 71801 CDGB/P4 is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Manufactured to P4 tolerance class, this bearing delivers superior dimensional stability and running accuracy. Its optimized design enables it to efficiently handle combined loads (radial and axial loads acting simultaneously) while maintaining high-speed performance up to 140,000 rpm. The light preload (Class B) minimizes deflection under operational loads, ensuring precise shaft positioning and enhanced system rigidity.

|---|---|---|
| CD | 15° Contact Angle | Optimized for handling combined radial and axial loads |
| GB | Light Preload (Class B) | Enhanced rigidity and reduced deflection under load |
| P4 | High Precision Tolerance Class | Superior running accuracy and dimensional stability |
71801 CDGB/P4 Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The phenolic resin cage provides excellent dimensional stability and reduced friction, contributing to smooth operation at high speeds. The P4 tolerance class ensures minimal runout and vibration for precision applications.
Optimized Load Capacity: With a 15° contact angle and 14 precision balls, this bearing effectively manages combined loads, offering a dynamic load rating of 468 lbf and static load rating of 266 lbf.
Universal Matching Capability: Designed as Universal Matchable (SU), these bearings can be mounted in sets of three to create preloaded bearing arrangements, providing maximum system rigidity and accuracy.
High-Speed Performance: The combination of phenolic cage, precision grinding, and optimized internal geometry enables operation at limiting speeds of 140,000 rpm.
