7006 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7006 CD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a light preload (Class B) matched set, it delivers optimized performance in high-speed spindle arrangements. Its P4A tolerance class ensures superior running accuracy, while the 15° contact angle provides excellent capability for handling combined loads—simultaneously supporting substantial radial forces and axial thrust in one direction. The phenolic cage contributes to smooth operation at the high limiting speed of 100,500 rpm.

7006 CD/P4ADGB Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring minimal runout and vibration for precision applications.
Optimized Load Capacity: The 15° contact angle and chrome steel construction provide a radial dynamic load rating of 5265 lbf and static load rating of 3600 lbf, making it suitable for applications with significant combined radial and axial loads.
High-Speed Performance: The phenolic cage and optimized internal geometry enable operation at limiting speeds up to 100,500 rpm, while the light preload ensures stable operation under high rotational velocities.
Universal Matching Capability: As a universal matchable (SU) bearing supplied in a matched pair, it simplifies installation and ensures optimal preload when mounted in back-to-back, face-to-face, or tandem arrangements.
