7013 CE/HCDGAVQ126 Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: Silicon nitride balls provide 60% less weight than steel balls, reducing centrifugal forces and enabling higher limiting speeds (24,000 rpm). Ceramic's non-conductive properties eliminate electrical arcing damage.
Precision Ground Surfaces: P4A tolerance class ensures minimal runout and vibration for superior rotational accuracy in precision applications.
Phenolic Cage Design: Offers excellent strength-to-weight ratio and operates effectively at high temperatures, contributing to stable high-speed performance.
Universal Matching Capability: Bearings are supplied as matched pairs (SU arrangement) with precisely controlled preload, ensuring optimal stiffness and accuracy when mounted in tandem.
Optimized Load Capacity: The 15° contact angle and modified raceway geometry provide balanced performance for combined radial and axial loads with dynamic load rating of 7,470 lbf.
