1310 ETN9 Bearing Product Overview & Core Advantages
The 1310 ETN9 is a double row angular contact ball bearing engineered for applications requiring high rigidity and exceptional performance under combined loads. This precision bearing features an open design optimized for high-speed operation, supported by a nylon cage (TN9) and factory-applied lubrication. Its compact bearing dimensions (50mm bore, 110mm OD, 27mm width) make it ideal for space-constrained, high-reliability installations where managing both radial and bidirectional axial loads is critical.

1310 ETN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior high rigidity support, enabling effective handling of combined loads including significant radial and bidirectional axial forces. With a dynamic load rating of 9810 lbf and static load rating of 3150 lbf, this bearing delivers reliable performance in demanding applications.
High-Speed Performance: The TN9 nylon cage minimizes centrifugal forces and friction, contributing to an impressive limiting speed of 8,000 rpm. Combined with factory-applied lubrication, this makes the 1310 ETN9 an excellent choice for high-speed applications.
Precision Engineering: Manufactured from chrome steel for both rings and balls, this bearing maintains dimensional stability and durability. The precise bearing dimensions and tight tolerances ensure consistent performance in precision machinery.
