1308 EKTN9 Bearing Product Overview & Core Advantages
The 1308 EKTN9 is a double row angular contact ball bearing engineered for applications requiring high radial load capacity and operational stability. Featuring an open design with a nylon cage (TN9), this precision bearing delivers reliable performance in demanding environments. Its double row construction provides high rigidity and enables it to accommodate combined loads effectively. With a limiting speed of 9,500 rpm and pre-lubrication, it is designed for durability and long service life in industrial machinery.

1308 EKTN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide superior stiffness, enabling the bearing to handle significant radial loads (dynamic: 7,605 lbf / static: 2,520 lbf) while maintaining dimensional stability.
High-Speed Performance: The TN9 nylon cage reduces centrifugal forces and friction, contributing to the excellent limiting speed of 9,500 rpm. This makes it ideal for high-speed applications requiring smooth operation.
Precision & Reliability: Manufactured from chrome steel with tight dimensional tolerances, this bearing ensures consistent performance and long service life. The open design allows for efficient lubrication management in various operating conditions.
