1311TNC3 Bearing Product Overview & Core Advantages
The 1311TNC3 is a double row angular contact ball bearing designed for applications requiring high load capacity and rigidity. This precision bearing excels at handling combined loads, simultaneously supporting significant radial forces and bidirectional axial loads. Its compact double-row design provides exceptional stiffness in a space-efficient package, making it ideal for high-reliability industrial applications. Manufactured with chrome steel components and featuring a C3 radial internal clearance, it accommodates thermal expansion in demanding operating conditions.
1311TNC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1311 | Standard bore diameter (55 mm) and dimension series |
| T | Nylon cage material for reduced weight and smooth operation |
| N | Snap ring groove on outer ring for secure axial positioning |
| C3 | Greater than normal radial internal clearance for thermal expansion |
1311TNC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to handle combined radial and axial loads from both directions. With a dynamic load rating of 11,408 lbf and static load rating of 4,050 lbf, it delivers reliable performance under heavy loading conditions.
Optimized High-Speed Performance: The nylon cage (T) reduces rotational mass and friction, contributing to the bearing's limiting speed of 7,500 rpm. The open design allows for efficient lubrication management in high-speed applications.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances (bore and OD tolerance: -0.015mm to 0), this bearing ensures consistent performance and long service life in precision machinery.
Versatile Mounting: The snap ring groove (N) facilitates secure axial positioning and simplifies installation in housing designs, while the C3 clearance accommodates thermal expansion in applications with elevated operating temperatures.
