7006 ACE/P4BVG275 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with a 25° contact angle provides excellent resistance to combined radial and axial loads. With a radial dynamic load rating of 1989 lbf and static rating of 1125 lbf, this bearing offers robust performance in demanding applications.
High-Speed Performance: The phenolic resin cage ensures stable operation at high rotational speeds, contributing to the bearing's limiting speed of 35,000 rpm. The optimized internal geometry minimizes friction and heat generation during high-speed operation.
Precision Engineering: Manufactured to P4 tolerance class with tight dimensional tolerances (bore: -0.005mm to 0, OD: -0.007mm to 0), this bearing guarantees exceptional running accuracy and minimal vibration for precision applications.
Material Excellence: Constructed from chrome steel for both rings and balls, the bearing delivers superior wear resistance and durability under high-stress conditions.
