7013 CE/HCP4AQBCB Bearing Structural Features & Performance Benefits
Enhanced Rigidity & Load Capacity: The quadruplex back-to-back arrangement creates an exceptionally rigid bearing system capable of withstanding heavy combined loads and significant moment loads. This configuration provides superior axial and radial stiffness for precision applications.
High-Speed Performance: The combination of ceramic balls and phenolic resin cage enables exceptional high-speed operation up to 31,000 rpm. Ceramic balls reduce centrifugal forces and thermal expansion, while the lightweight cage minimizes inertial effects.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control (bore diameter tolerance: -0.004mm to 0), this bearing ensures minimal runout and vibration for applications requiring extreme accuracy.
Optimized Preload: The light preload (Class B) provides consistent rotational accuracy while minimizing friction and heat generation, contributing to extended service life and reliable performance.
