S7003 ACD/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double-row angular contact design provides superior rigidity and enables the bearing to support significant combined loads and bidirectional axial thrust.
Enhanced High-Speed Performance: The combination of lightweight phenolic cage, low-friction ceramic balls, and optimized grease lubrication contributes to an exceptionally high limiting speed of 103,000 rpm.
Precision & Longevity: Manufactured to P4A tolerance class for minimal runout and vibration. The sealed construction with pre-applied grease protects against contamination and offers long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
Universal Matchability (SU): Bearings are universally matchable, allowing for flexible mounting arrangements (back-to-back, face-to-face, or tandem) to achieve the required preload and stiffness without selective assembly.
