7024 CD/P4ADGD Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The angular contact design with heavy preload provides exceptional system stiffness, minimizing deflection under load. Manufactured to P4A tolerance class with tight dimensional control (bore/OD tolerance: -0.004mm to 0), ensuring precise rotational accuracy.
Superior Load Capacity: With a 15° contact angle and optimized internal geometry, this bearing efficiently handles combined radial and axial loads. Dynamic load rating of 42,750 lbf and static load rating of 55,125 lbf ensure reliable performance in demanding applications.
High-Speed Capability: The phenolic cage and optimized internal design enable operation at limiting speeds up to 16,000 rpm. The open structure facilitates efficient lubrication and heat dissipation.
Universal Matching: As a Universal Matchable (SU) bearing, pairs can be arranged in back-to-back, face-to-face, or tandem configurations without selective assembly, simplifying installation and maintenance.
