1206 EKTN9/C3 Bearing Product Overview & Core Advantages
The 1206 EKTN9/C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precision. This metric bearing features a tapered bore (1:12) for secure shaft mounting and is pre-lubricated for immediate operation. Its primary advantage lies in its ability to accommodate significant radial loads while maintaining high running accuracy. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or heavy load conditions, ensuring reliable performance and long service life in demanding environments.
1206 EKTN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
| 1206 | Standard bearing designation (30mm bore, 62mm OD) | Standardized bearing dimensions for easy replacement |
| EK | Tapered bore (1:12) | Secure mounting on tapered adapter sleeves |
| TN9 | Nylon cage, glass fiber reinforced | Reduced friction, suitable for high-speed applications |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and heavy loads |
1206 EKTN9/C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior rigidity compared to single row bearings, enabling stable operation under substantial radial loads (Dynamic: 3510 lbf, Static: 1046 lbf). This makes it ideal for applications where shaft deflection must be minimized.
Optimized High-Speed Performance: The TN9 nylon cage offers excellent strength-to-weight ratio and low friction, contributing to the bearing's limiting speed of 15,000 rpm. The cage design ensures smooth ball guidance and reduced centrifugal forces at high rotational speeds.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing delivers consistent performance and durability. The tight dimensional tolerances on bore, outside diameter, and width ensure precise fit and reliable operation in precision machinery.
Ready-to-Install Operation: The bearing comes pre-lubricated and features an open design, making it immediately operational upon installation while allowing for specific lubrication regimes if required by the application.
1206 EKTN9/C3 Bearing Typical Application Areas
The 1206 EKTN9/C3 is engineered for demanding industrial applications where precision, speed, and reliability are critical. Key application areas include:
- Electric Motors & Generators: Particularly in medium-sized motors requiring high-speed operation and radial load capacity.
- Industrial Gearboxes: For supporting gears and shafts where thermal expansion and heavy loads are present.
- Material Handling Equipment: Conveyor systems, pulley assemblies, and other machinery requiring robust bearing solutions.
- Agricultural Machinery: Implement drives and PTO shafts where contamination resistance and durability are essential.
- Industrial Fans & Blowers: Applications requiring balanced performance at moderate to high rotational speeds.
