1204 EKTN9/C3 Bearing Product Overview & Core Advantages
The 1204 EKTN9/C3 is a metric double row angular contact ball bearing engineered for applications requiring high precision and robust performance. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing excels at handling combined radial and axial loads simultaneously. Its compact design, coupled with C3 radial internal clearance and factory-applied lubrication, ensures reliable operation in demanding conditions, making it an ideal choice for high-rigidity and precision machinery.
1204 EKTN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1204 | Standard bore diameter 20 mm, outside diameter 47 mm |
| EK | Optimized internal design with reinforced shoulders |
| TN9 | Nylon cage, glass fiber reinforced, suitable for high-speed operation |
| C3 | Greater than normal radial internal clearance for thermal expansion |
1204 EKTN9/C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing construction provides superior radial stiffness and can accommodate significant combined loads. With a dynamic load rating of 2858 lbf and static load rating of 765 lbf, it delivers reliable performance under varying operational stresses.
Optimized High-Speed Performance: The TN9 nylon cage reduces friction and enables smooth operation at limiting speeds up to 20,000 rpm. The factory-applied lubrication ensures consistent performance across the entire temperature range (-30° to 110°C).
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.01mm to 0), this bearing maintains precise running accuracy. The C3 clearance accommodates thermal expansion in high-speed applications.
