7201 ACD/P4ADGC Bearing Product Overview & Core Advantages
The 7201 ACD/P4ADGC is a precision angular contact ball bearing designed for high-performance applications requiring exceptional rotational accuracy and rigidity. This universal matchable bearing features a P4A tolerance class and a 25° contact angle, enabling it to handle combined radial and axial loads simultaneously. Its moderate preload (Class C) ensures high system stiffness and minimal deflection under operational stresses. Manufactured from chrome steel and featuring a phenolic cage, this bearing is optimized for high-speed operation up to 95,000 rpm, making it ideal for demanding precision machinery.

7201 ACD/P4ADGC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design and moderate preload provide excellent resistance to deflection, supporting substantial combined loads. With a dynamic load rating of 2077 lbf and static load rating of 1102 lbf, it delivers reliable performance under demanding conditions.
Optimized High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, while the precise P4A tolerance ensures smooth operation at limiting speeds of 95,000 rpm. The 25° contact angle optimally balances axial and radial load capacity for high-speed applications.
Precision Engineering: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers superior durability and wear resistance. The universal matching capability (SU) enables flexible mounting configurations without requiring selective assembly.
