7024 ACD/P4AQFCA Bearing Product Overview & Core Advantages
The 7024 ACD/P4AQFCA is a high-precision quadruplex angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This P4A tolerance class bearing features a face-to-face (QFC) matched arrangement of four bearings, providing superior stability and load distribution. Its core advantage lies in its ability to handle combined radial and axial loads simultaneously with high running accuracy, making it ideal for ultra-precision, high-rigidity systems. The extra light preload (Class A) ensures minimal deflection and smooth operation under high-speed conditions.

7024 ACD/P4AQFCA Bearing Structural Features & Performance Benefits
Exceptional Rigidity & Load Capacity: The quadruplex face-to-face configuration creates an extremely rigid bearing system capable of withstanding heavy combined loads and moments. With a radial dynamic load rating of 65,475 lbf and static load rating of 104,625 lbf, this bearing delivers reliable performance under demanding conditions.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control (bore/OD tolerance: -0.004mm to 0), ensuring minimal runout and vibration for precision applications.
High-Speed Capability: The phenolic cage material and optimized 25° contact angle enable stable operation at limiting speeds up to 10,000 rpm, making it suitable for high-speed spindle applications.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, providing excellent wear resistance and durability across the operating temperature range of -30°C to 110°C.
