7016 CE/HCP4ALDBA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The combination of chrome steel rings and ceramic balls significantly reduces friction, heat generation, and wear, enabling higher limiting speeds (28,000 rpm) and extended service life.
Duplex Back-to-Back Configuration: This matched set arrangement provides exceptional rigidity and moment load capacity, making it suitable for applications requiring precise shaft positioning and minimal deflection.
Phenolic Cage: The phenolic resin cage offers excellent dimensional stability at high speeds and operates effectively within the specified temperature range (-30°C to 110°C).
Precision Engineering: With P4A tolerance class and tight dimensional tolerances, this bearing ensures smooth, quiet operation and minimal vibration for high-precision applications.
