7022 ACD/P4AQBCC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The quadruplex back-to-back configuration creates an extremely rigid bearing system capable of withstanding heavy combined radial and axial loads as well as significant moment loads. This design provides optimal load distribution across all four bearing rows.
Precision Performance: Manufactured to P4A tolerance standards, this bearing delivers exceptional running accuracy and minimal vibration. The 25° contact angle is optimized for handling substantial axial loads while maintaining radial load capacity.
High-Speed Capability: The phenolic cage material provides excellent strength-to-weight ratio, reducing centrifugal forces and enabling stable operation at the limiting speed of 16,250 rpm.
Material Excellence: Constructed from chrome steel for both rings and balls, ensuring high durability, wear resistance, and long service life under demanding conditions.
