7036 ACD/P4ADBB Bearing Structural Features & Performance Benefits
High Rigidity & Preload: The duplex back-to-back (DB) arrangement provides a rigid, moment-resisting bearing system. The light preload (Class B) eliminates internal clearance, ensuring precise shaft positioning and reducing vibration under high-speed operation.
Superior Load Capacity: The 25° contact angle and robust construction enable the bearing to support significant combined radial and axial loads in both directions.
Optimized High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed. The bearing is supplied lubricated for immediate operation.
Precision & Longevity: Manufactured to P4A tolerance with chrome steel rings and balls, this bearing ensures consistent, high-accuracy performance and extended service life in precision machinery.
