S7010 CD/P4ADGA Bearing Structural Features & Performance Benefits
Double Row Design for Enhanced Rigidity: The double row angular contact configuration provides superior stiffness and stability compared to single row bearings, making it ideal for applications requiring precise shaft positioning and reduced deflection under load.
Optimized Load Capacity: With a 15° contact angle and double row ball complement, this bearing efficiently handles combined radial and axial loads from both directions simultaneously. The radial dynamic load rating of 10,980 lbf and static rating of 10,800 lbf ensure reliable performance in demanding operating conditions.
High-Speed Performance: The phenolic resin cage and precision-ground chrome steel components enable operation at limiting speeds up to 46,000 rpm. The optimized internal geometry and grease lubrication contribute to reduced friction and heat generation at high rotational speeds.
Precision Engineering: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, this bearing delivers exceptional dimensional accuracy and running precision for critical applications.
