7022 CE/P4ATBTA Bearing Product Overview & Core Advantages
The 7022 CE/P4ATBTA is a precision angular contact ball bearing specifically designed for applications demanding exceptional rigidity and accuracy. This bearing is supplied as a triplex back-to-back (TBT) matched set, delivering superior performance under combined loads (radial and axial). Manufactured to the stringent P4A tolerance class, it offers extremely tight dimensional control for high-precision machinery. Its extra light preload (Class A) ensures minimal running torque and optimal performance in high-speed applications, making it an ideal choice for machine tool spindles and other precision equipment.

7022 CE/P4ATBTA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The triplex back-to-back configuration creates an extremely rigid bearing system capable of withstanding heavy combined radial and axial loads from multiple directions. This arrangement provides exceptional moment stiffness, crucial for maintaining precision under operational stresses.
Precision Engineering: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, this bearing ensures minimal runout and vibration. The 15° contact angle optimizes the balance between radial and axial load capacity.
High-Speed Capability: Featuring a phenolic cage and extra light preload, this bearing achieves a limiting speed of 10,000 rpm. The phenolic cage offers excellent strength-to-weight ratio and operates smoothly at high rotational speeds.
Premium Materials: Constructed from chrome steel for both rings and balls, this bearing delivers superior wear resistance and long service life. The 30 precision-ground balls with 12.7mm diameter ensure optimal load distribution.
