S71926 ACD/HCP4ADGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design and 25° contact angle provide high rigidity and enable the bearing to handle substantial combined radial and axial loads from both directions, ensuring stable operation under complex loading conditions.
High-Speed Performance: The combination of a lightweight phenolic cage and ceramic balls significantly reduces centrifugal forces and friction, enabling a high limiting speed of 11,000 rpm. The hybrid construction also reduces heat generation at high speeds.
Precision & Longevity: Manufactured to a P4A tolerance class, this bearing guarantees exceptional running accuracy and low vibration. The sealed design with grease lubrication protects against contamination and provides a long service life within a wide operating temperature range (-30°C to 110°C).
