707 CE/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings with ceramic balls significantly reduces friction, minimizes heat generation, and extends service life under high-speed conditions. This construction also provides excellent electrical insulation properties.
Precision Engineering: Manufactured to P4 tolerance class with precise bearing dimensions (7mm bore, 19mm OD, 6mm width), ensuring consistent performance and easy integration into precision assemblies.
High-Speed Capability: The phenolic resin cage and ceramic balls enable exceptional limiting speeds up to 230,000 rpm, while the optimized internal geometry maintains stability at high rotational velocities.
Superior Load Capacity: With a radial dynamic load rating of 439 lbf and radial static load rating of 144 lbf, this bearing reliably handles combined loads in demanding applications.
Preload Availability: Designed to accommodate preload for enhanced stiffness and reduced deflection in precision positioning systems.
