1305 EKTN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to handle substantial combined loads (4275 lbf dynamic, 1215 lbf static ratings). This makes it exceptionally stable under complex loading conditions.
High-Speed Performance: The TN9 nylon cage ensures optimal performance at high rotational speeds (limiting speed: 15,000 rpm), offering excellent strength-to-weight ratio and reduced centrifugal forces for smooth operation.
Precision Engineering: Manufactured from chrome steel for both rings and balls, with tight dimensional tolerances (bore: -0.01mm to 0), this bearing delivers consistent precision and long service life in demanding applications.
Temperature Compatibility: Operating temperature range of -30°C to 110°C ensures reliable performance across various industrial environments and conditions.
