1206 EKTN9/W64 Bearing Product Overview & Core Advantages
The 1206 EKTN9/W64 is a metric double row angular contact ball bearing engineered for high-performance applications requiring exceptional rigidity and precision. Its double row design enables it to support significant combined loads—simultaneously handling radial forces and axial loads in both directions. Featuring a tapered bore (1:12) and an open construction, this bearing is optimized for precise mounting on tapered shafts, ensuring maximum stability and accuracy in demanding operational environments. Its high limiting speed and robust construction make it an ideal choice for applications where reliability and long service life are critical.
1206 EKTN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1206 | Standard bearing designation indicating bore diameter (30 mm) and dimension series. |
| EK | Optimized internal design for enhanced load capacity and performance. |
| TN9 | Nylon cage, glass fiber reinforced. Provides reduced weight, lower friction, and excellent performance at high speeds. |
| W64 | Indicates the bearing is pre-lubricated with a specific, high-performance grease suitable for the specified temperature range. |
1206 EKTN9/W64 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact construction provides superior rigidity, enabling the bearing to handle significant combined radial and axial loads without sacrificing performance.
- Precision Tapered Bore: The 1:12 taper allows for precise interference fit on a tapered shaft or adapter sleeve, ensuring a secure mount, minimizing inner ring creep, and enhancing overall system accuracy.
- Optimized High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces, lowers operating temperatures, and allows for a higher limiting speed (15,000 rpm).
- Ready-to-Install & Reliable: The bearing is supplied pre-lubricated, ensuring immediate operation and reducing initial setup time. The open design allows for re-lubrication in service if required by the application.
