S71914 ACB/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The double row angular contact design provides exceptional stiffness and running accuracy under P4A tolerance class, ensuring minimal deflection during operation. The 25° contact angle optimizes load distribution for both radial and axial forces.
Superior Load Capacity: Engineered to handle combined radial and axial loads simultaneously, with a dynamic load rating of 4770 lbf and static load rating of 5310 lbf. The universal matching (SU) arrangement allows for precise preload control in paired installations.
High-Speed Capability: The phenolic cage material and optimized internal geometry enable reliable operation at limiting speeds up to 22,000 rpm. The sealed construction with grease lubrication maintains consistent performance at high rotational velocities.
Enhanced Service Life: Manufactured from chrome steel for both rings and balls, providing excellent wear resistance and durability. The pre-lubricated and sealed design ensures long-term reliability with minimal maintenance requirements.
