S71906 ACDTP/HCP4B Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The 25° contact angle and preloaded DTP arrangement provide superior axial and radial stiffness, enabling the bearing to handle significant combined loads with minimal deflection.
High-Speed Performance: The combination of ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic cage allows for a high limiting speed of 36,000 rpm. This makes it suitable for demanding high-speed applications.
Precision & Longevity: Manufactured to a P4 (ABEC-7) tolerance class, this bearing ensures minimal runout and vibration. The hybrid ceramic design offers enhanced durability, reduced wear, and the ability to operate in a wide temperature range from -30°C to 110°C.
Sealed & Lubricated: The bearing is sealed and comes pre-lubricated, protecting against contamination and providing long-term, maintenance-free operation.
