1310 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 effectively. With a radial dynamic load rating of 9810 lbf and static load rating of 3150 lbf, it ensures reliable performance under demanding conditions.
High-Speed Performance: The TN9 nylon cage contributes significantly to the bearing's ability to operate at limiting speeds of 8,000 rpm. This cage design reduces centrifugal forces and maintains stability at high rotational speeds.
Precision Engineering: Manufactured with tight dimensional tolerances (bore: -0.012mm to 0, outside diameter: -0.015mm to 0) and optimal shoulder diameters (inner: 70.3 mm, outer: 92.6 mm), ensuring precise fitment and alignment in applications.
Material Excellence: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability. The bearing comes pre-lubricated for immediate operation within a wide temperature range of -30° to 110°C.
