7000 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7000 CD/P4ADGB is a precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This universal matchable (SU) bearing features a 15° contact angle and light preload (Class B), making it ideal for arrangements requiring high rigidity and precise rotational characteristics. Its P4A tolerance class ensures superior dimensional and running accuracy, while the phenolic cage contributes to excellent high-speed capability. This bearing is pre-lubricated and operates effectively within a temperature range of -30°C to 110°C.

7000 CD/P4ADGB Bearing Structural Features & Performance Benefits
High Precision & Rigidity: Manufactured to P4A tolerance class with a light preload, this bearing delivers exceptional running accuracy and minimizes deflection under load, providing superior system stiffness.
Optimized High-Speed Performance: The lightweight phenolic resin cage ensures stable operation and reduced centrifugal forces at high speeds, supporting a limiting speed of 185,000 rpm. The 15° contact angle provides an excellent balance between radial and axial load capacity.
Universal Matching Capability (SU): The DGB suffix indicates that these bearings are universally matchable. Any two bearings can be paired without selective assembly, simplifying inventory and installation for duplex arrangements to handle combined loads and moments.
Superior Material Construction: Made from chrome steel for both rings and balls, this bearing offers high durability and wear resistance, ensuring long service life in precision applications.
