7003 CEGA/P4A Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring exceptional dimensional accuracy and minimal runout for high-precision applications.
High-Speed Capability: The phenolic resin cage provides excellent dimensional stability at high speeds, contributing to the impressive limiting speed of 115,000 rpm. The optimized internal geometry and 15° contact angle reduce friction and heat generation during high-speed operation.
Superior Load Capacity: With a dynamic load rating of 1,316 lbf and static load rating of 574 lbf, this bearing delivers reliable performance under combined radial and axial loads. The angular contact design efficiently handles thrust loads in one direction while maintaining radial load capacity.
Material Excellence: Constructed from chrome steel for both rings and balls, providing high hardness, wear resistance, and dimensional stability. The open design allows for customized lubrication schemes tailored to specific application requirements.
