1309 EKTN9 Bearing Product Overview & Core Advantages
The 1309 EKTN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open design without integral seals, making it ideal for systems where external sealing is provided. Its double row construction enables it to accommodate significant combined loads—handling both radial forces and bidirectional axial loads simultaneously. This results in exceptional rigidity and stable operation in demanding environments. Pre-lubricated and ready for installation, it offers reliable performance across a broad temperature range from -30°C to 110°C.

1309 EKTN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides superior stiffness and enables the bearing to handle substantial combined radial and axial loads in both directions. With a dynamic load rating of 8775 lbf and static load rating of 3015 lbf, it delivers robust performance in heavy-duty applications.
High-Speed Performance: The TN9 nylon cage reduces centrifugal forces and friction, contributing to an impressive limiting speed of 8,500 rpm. This makes it an excellent choice for high-speed precision applications.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing ensures consistent performance and long service life. The precise dimensional tolerances (bore: -0.012mm to 0, OD: -0.015mm to 0) guarantee accurate fit and optimal performance in precision assemblies.
Maintenance Features: While being an open type bearing, it comes pre-lubricated for immediate use and can be easily integrated into existing lubrication systems for continuous operation.
