71914 CD/P4ATGC Bearing Structural Features & Performance Benefits
High Rigidity & Precision: Manufactured to P4A tolerance standards with precise bearing dimensions (70mm bore, 100mm OD), this bearing ensures minimal runout and vibration. The 15° contact angle and optimized internal geometry provide excellent stiffness against complex loading conditions.
Superior Load Capacity: With a dynamic load rating of 16,672 lbf and static load rating of 22,950 lbf, the 71914 CD/P4ATGC reliably handles significant combined radial and axial loads. The arrangement of 24 chrome steel balls with a diameter of 9.525mm ensures even load distribution.
High-Speed Performance: The phenolic cage contributes to lower friction and higher limiting speeds (24,000 rpm), making it suitable for high-speed applications. The cage's lightweight construction reduces centrifugal forces at elevated rotational speeds.
Universal Matching Capability: As a Universal Matchable (SU) bearing, it can be paired with other identical bearings in various configurations (DB, DF, DT) to achieve specific preload and stiffness requirements without selective matching.
