1205 EKTN9/C3 Bearing Product Overview & Core Advantages
The 1205 EKTN9/C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precision. Featuring a tapered bore (1:12) and open construction, this metric bearing excels in handling combined loads while maintaining dimensional stability. Its optimized internal geometry and C3 radial internal clearance make it suitable for demanding industrial environments where reliable performance under varying thermal and load conditions is essential.
1205 EKTN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1205 | Standard bore diameter (25 mm) and series designation |
| EK | Optimized internal design for enhanced load capacity |
| TN9 | Glass fiber reinforced nylon cage for high-speed operation |
| C3 | Greater radial internal clearance for thermal expansion compensation |
1205 EKTN9/C3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior radial and axial stiffness, ensuring stable shaft support under combined loading conditions.
Optimized Load Capacity: Engineered internal geometry enables efficient distribution of radial dynamic loads (3218 lbf) and static loads (900 lbf).
High-Speed Capability: The TN9 nylon cage reduces centrifugal forces and friction, supporting limiting speeds up to 18,000 rpm.
Precision Engineering: Tight dimensional tolerances on bore diameter (-0.01mm to 0) and outside diameter (-0.013mm to 0) ensure precise fit and alignment.
Thermal Compensation: C3 clearance accommodates thermal expansion in high-speed or temperature-varying applications.
