1313 EKTN9/C3 Bearing Product Overview & Core Advantages
The 1313 EKTN9/C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. Its metric design features a tapered bore (1:12) for secure shaft mounting, enabling it to handle significant radial loads while maintaining precision. Constructed from high-grade chrome steel and featuring a nylon cage, this bearing offers an optimized balance of strength, speed capability, and operational smoothness. The C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used, ensuring consistent performance across its operating temperature range.
1313 EKTN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1313 | Standard bearing series designation, indicating the core dimensions (65mm bore, 140mm OD, 33mm width). |
| EK | Designates an optimized internal geometry and a pressed steel cage (superseded by TN9 in this specific model, indicating a design evolution). |
| TN9 | Indicates the use of a glass fiber reinforced polyamide (nylon) cage. This cage design is lightweight, promotes lower friction, and is ideal for high-speed operation. |
| C3 | Specifies a greater than normal radial internal clearance. This is crucial for applications involving thermal expansion, heavy interference fits, or where operational heat generation is expected, preventing preload and seizure. |
1313 EKTN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial stiffness compared to single row bearings, making it exceptionally resistant to deflection under heavy radial loads. This construction is fundamental for maintaining accuracy in precision machinery.
- High-Speed Performance: The TN9 nylon cage is a key contributor to the bearing's high limiting speed of 6,000 rpm. Its lightweight nature and excellent sliding properties reduce centrifugal forces and friction, enabling smoother and cooler operation at high rotational velocities.
- Tapered Bore for Secure Mounting: The 1:12 tapered bore allows for precise axial positioning and a tight, slip-free fit on adapter sleeves or tapered shafts, essential for applications with high torque or vibrational loads.
- Optimized for Challenging Conditions: The specified C3 clearance and the robust chrome steel construction ensure reliable performance in applications prone to thermal fluctuations or where tight fits are required, enhancing operational longevity and reliability.
