2205 EKTN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and stability, enabling the bearing to handle significant combined loads with minimal deflection. With a dynamic load rating of 3780 lbf and static load rating of 990 lbf, it offers reliable performance under demanding conditions.
High-Speed Performance: The TN9 nylon cage ensures smooth operation at high rotational speeds up to 18,000 rpm. The lightweight construction reduces centrifugal forces, while the pre-applied lubrication maintains consistent performance throughout the speed range.
Precision Engineering: Manufactured with tight dimensional tolerances (bore: -0.01mm to 0, OD: -0.013mm to 0) and chrome steel components, this bearing delivers exceptional running accuracy and long service life in precision applications.
