S7014 FE/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides exceptional stiffness and can handle significant combined loads with an 18° contact angle. The universal matching capability allows for optimal load distribution in various mounting arrangements.
High-Speed Performance: The combination of ceramic balls (reducing centrifugal forces and friction) and phenolic cage enables superior high-speed operation up to 22,000 rpm. The lightweight construction minimizes inertial effects at extreme rotational speeds.
Precision & Longevity: Manufactured to P4A tolerance class with tight dimensional control (bore: -0.004mm to 0, OD: -0.004mm to 0), ensuring precise running accuracy. The sealed design with factory-applied grease provides maintenance-free operation and protects against contamination throughout the bearing's service life.
Thermal Stability: The hybrid ceramic construction offers excellent thermal characteristics, maintaining dimensional stability across the operating temperature range of -30°C to 110°C.
