1206KTN Bearing Product Overview & Core Advantages
The 1206KTN is a double row angular contact ball bearing designed for applications requiring high precision and robust performance. Featuring a 1:12 tapered bore for secure shaft mounting, this metric bearing delivers exceptional high rigidity and can accommodate combined loads (radial and axial). Its compact design, with optimized bearing dimensions (30mm bore, 62mm OD, 16mm width), makes it ideal for space-constrained, high-reliability machinery. The nylon cage and factory-applied lubrication contribute to its smooth operation and longevity.
1206KTN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1206 | Standard bearing series designation, indicating the core dimensions (30mm bore, 62mm OD). |
| K | Denotes a tapered bore with a 1:12 taper ratio, enabling precise axial positioning and a tight interference fit on the shaft. |
| TN | Indicates the cage material is Nylon (Polyamide), which is lightweight, reduces friction, and is suitable for high-speed operation. |
1206KTN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior radial stiffness and enables the bearing to handle significant combined loads, making it more robust than single-row designs.
- Precision Tapered Bore: The 1:12 tapered bore ensures a secure, concentric fit on the shaft, minimizing slippage and maintaining alignment under heavy loads and high speeds.
- High-Speed Performance: The lightweight nylon (TN) cage minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 15,000 rpm.
- Optimized Material & Lubrication: Constructed from chrome steel for both rings and balls, ensuring high durability and fatigue resistance. The bearing is pre-lubricated for immediate use and reliable operation within its specified temperature range.
1206KTN Bearing Typical Application Areas
This bearing is engineered for demanding applications across various industries, including:
- Electric Motors & Generators: Ideal for rotor support where high speeds and combined loads are present.
- Precision Machine Tool Spindles: Provides the necessary rigidity and speed for high-precision machining centers.
- Agricultural & Construction Machinery: Used in gearboxes, pulleys, and other components requiring robust performance in harsh environments.
- Material Handling Equipment: Suitable for conveyor systems and pulley drives that demand reliable operation under radial and axial loads.
