S7013 ACD/HCP4A Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The combination of a 25° contact angle and an applied preload provides exceptional system stiffness, minimizing deflection under load for superior positional accuracy.
Superior High-Speed Performance: The hybrid ceramic design with lightweight ceramic balls and a phenolic resin cage significantly reduces centrifugal forces, enabling a high limiting speed of 15,000 rpm. This makes it an ideal high-speed bearing.
Excellent Load Capacity: Designed as an angular contact bearing, it efficiently supports combined radial and axial loads, with a dynamic load rating of 8775 lbf and a static load rating of 7988 lbf.
Maintenance-Free Operation: The sealed and pre-lubricated design protects against contamination and retains lubricant, ensuring consistent performance and a long service life without the need for re-lubrication.
