7006 CD/HCP4ADGA Bearing Product Overview & Core Advantages
The 7006 CD/HCP4ADGA is a precision angular contact ball bearing engineered for applications demanding exceptional accuracy and high-speed performance. This universal matchable (SU) bearing is designed to accommodate combined loads—simultaneously handling radial loads and axial loads in one direction—making it ideal for high-rigidity, high-reliability systems. Its P4A tolerance class ensures superior dimensional and running accuracy, while the ceramic ball and phenolic cage construction contribute to reduced friction, lower operating temperatures, and extended service life under demanding conditions.

7006 CD/HCP4ADGA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings with silicon nitride (Si3N4) ceramic balls significantly reduces friction, minimizes heat generation, and provides excellent electrical insulation properties. This construction enables higher limiting speeds (71,500 rpm) and extended service life compared to all-steel bearings.
High Rigidity & Load Capacity: The angular contact design with 15° contact angle provides optimal stiffness for applications requiring precise shaft positioning. With a dynamic load rating of 5265 lbf and static load rating of 3600 lbf, this bearing reliably handles combined radial and axial loads.
Precision Performance: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), this bearing ensures minimal runout and vibration for superior rotational accuracy.
High-Speed Capability: The phenolic resin cage offers excellent strength-to-weight ratio and smooth operation at high speeds, while the open design allows for efficient lubrication management in high-speed applications.
