1213 EKTN9/C3 Bearing Product Overview & Core Advantages
The 1213 EKTN9/C3 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance under combined radial and axial loads. Featuring a tapered bore and a C3 radial internal clearance, it is optimized for precise interference fits on shafts, ensuring stable operation. Its nylon cage (TN9) and factory-applied lubrication contribute to smooth, high-speed operation up to 7,000 rpm, making it an ideal choice for demanding industrial environments.
1213 EKTN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1213 | Basic bearing code indicating metric dimensions (65mm bore, 120mm OD, 23mm width) |
| EK | Optimized internal design for enhanced load capacity and performance |
| TN9 | Nylon cage, glass fiber reinforced, suitable for high speeds and offering good guiding properties |
| /C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or heavy interference fits |
1213 EKTN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides superior radial and axial stiffness, effectively handling combined loads from multiple directions. With a dynamic load rating of 7898 lbf and static load rating of 3150 lbf, it ensures reliable performance in heavy-duty applications.
- Optimized High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces and friction, enabling stable operation at the limiting speed of 7,000 rpm. The factory-applied lubrication further supports smooth, high-velocity rotation.
- Precision Tapered Bore: The 1:12 taper bore allows for precise axial positioning and secure shaft mounting via an adapter sleeve or withdrawal sleeve, accommodating shaft interference fits effectively.
- Robust Material Construction: Manufactured from chrome steel for both rings and balls, the bearing offers high wear resistance and durability, operating reliably within a temperature range of -30°C to 110°C.
