7006 CD/P4ADFC Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 15° contact angle is engineered to efficiently handle combined radial and axial loads, providing versatile load-carrying capacity in compact assemblies.
Enhanced System Rigidity: The duplex face-to-face (DF) arrangement with moderate preload (Class C) creates a highly rigid bearing system that effectively resists moment loads and minimizes shaft deflection under operational stresses.
Precision Performance: Manufactured to P4A tolerance class with phenolic cage construction, this bearing ensures smooth operation at high speeds (up to 56,000 rpm) with minimal vibration and heat generation.
Superior Material Selection: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability under demanding operating conditions within the temperature range of -30°C to 110°C.
