1311TN Bearing Product Overview & Core Advantages
The 1311TN metric double row angular contact ball bearing represents a high-performance solution for applications requiring exceptional rigidity and the ability to handle combined loads. Its double row design enables it to support significant radial loads alongside bidirectional axial loads simultaneously, making it ideal for precision machinery. With its open construction and optimized nylon cage, this bearing is engineered for high-speed operation up to 7,500 rpm, delivering reliable performance in demanding environments. The pre-lubricated design ensures immediate operation and long service life.
1311TN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1311 | Standard bearing series designation indicating bearing dimensions: 55mm bore, 120mm OD, 29mm width |
| TN | Nylon (polyamide) cage, providing excellent high-speed performance and reduced friction |
1311TN Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact construction provides superior stiffness, enabling stable operation under combined radial and axial loads. With a dynamic load rating of 11,408 lbf and static load rating of 4,050 lbf, this bearing delivers robust performance in demanding applications.
Optimized High-Speed Performance: The TN nylon cage reduces rotational mass and friction, contributing to the bearing's exceptional limiting speed of 7,500 rpm. This makes the 1311TN ideal for high-speed machinery where precision and reliability are critical.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing offers consistent performance and durability. The standard CN radial internal clearance ensures optimal operation across typical industrial temperature ranges from -30°C to 110°C.
