S7005 CD/P4ADGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double-row design provides superior rigidity and enables the bearing to support significant combined loads—both radial and axial forces from both directions. This makes it exceptionally stable under complex loading conditions.
High-Speed Performance: The use of a lightweight, robust phenolic cage minimizes centrifugal forces and friction, contributing to the high limiting speed of 83,000 rpm. The optimized internal geometry further enhances high-speed capability.
Precision & Longevity: Manufactured to P4A tolerances with chrome steel rings and balls, this bearing ensures minimal runout and vibration. It comes sealed and pre-lubricated with grease, protecting against contamination and providing long-term, maintenance-free operation within a wide temperature range.
