126 TN9 Bearing Product Overview & Core Advantages
The 126 TN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open design and is pre-lubricated, enabling it to handle significant combined loads—both radial and axial forces—simultaneously. Its compact dimensions (6mm bore, 19mm OD, 6mm width) and high limiting speed of 45,000 rpm make it an ideal solution for space-constrained, high-speed applications demanding high rigidity and stable operation.

126 TN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to support substantial combined loads with minimal deflection. With a dynamic load rating of 556 lbf and static load rating of 108 lbf, it delivers reliable performance under demanding conditions.
High-Speed Performance: The TN9 nylon cage minimizes centrifugal forces and friction, contributing to the exceptional limiting speed of 45,000 rpm. This makes it an excellent high-speed bearing choice.
Precision & Durability: Manufactured from chrome steel for both rings and balls, the bearing offers high wear resistance and dimensional stability. The precise bearing dimensions and tight tolerances ensure consistent performance in precision assemblies.
Maintenance Features: The bearing comes pre-lubricated, providing immediate operation and reducing initial setup time. The open seal type allows for relubrication if required by specific application conditions.
