71916 FE/HCP4ALDBA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement creates a wide, rigid support system that effectively resists moment loads and combined radial and axial loads. The 18° contact angle is optimized for high axial load capacity.
High-Speed & Low-Friction Performance: The use of ceramic balls (Hybrid Ceramic) significantly reduces centrifugal forces and friction, enabling a high limiting speed of 28,000 rpm. The lightweight phenolic cage further enhances high-speed stability and reduces vibration.
Precision & Longevity: Manufactured to P4A tolerance class with tight dimensional tolerances, this bearing ensures minimal runout and smooth operation. The combination of chrome steel rings and ceramic balls provides excellent wear resistance and a long operational life.
