7006 CE/HCP4AH1DT Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings with silicon nitride (Si3N4) ceramic balls significantly reduces centrifugal forces, enabling higher rotational speeds while providing excellent wear resistance and electrical insulation properties.
Phenolic Resin Cage: The lightweight phenolic cage offers superior strength-to-weight ratio, excellent dimensional stability at high temperatures, and reduced friction for enhanced high-speed performance.
Precision Engineering: With P4A tolerance class and tight dimensional controls (bore/OD tolerance: -0.004mm to 0), this bearing ensures minimal runout and vibration for precision applications.
Duplex Tandem Configuration: The DT arrangement provides maximum axial stiffness and load capacity in one direction, making it ideal for applications requiring high thrust load capability while maintaining radial support.
Optimized Load Distribution: Featuring 17 ceramic balls of 6.35mm diameter with 15° contact angle, the bearing delivers balanced radial and axial load capacity (3398 lbf dynamic, 2340 lbf static).
