11206TN Bearing Product Overview & Core Advantages
The 11206TN is a double row angular contact ball bearing designed for applications requiring high rigidity and precision. This metric bearing features an open design and is pre-lubricated for immediate use. Its primary advantage lies in its ability to support significant combined loads—handling both radial forces and bidirectional axial loads simultaneously. Constructed with a nylon cage and manufactured from high-grade chrome steel, it offers reliable performance, making it suitable for high-speed applications and scenarios demanding dimensional stability and long service life.
11206TN Bearing Model Code Explained, Specifications & Naming Convention
The model number 11206TN can be broken down as follows:
- 11: Series designation, indicating a specific internal design and dimensional series for double row angular contact ball bearings.
- 2: Size series code related to the cross-sectional dimensions.
- 06: Bore diameter code. "06" corresponds to a 30 mm bore diameter (06 * 5 = 30 mm).
- TN: Cage type designation. "TN" indicates a molded nylon cage, which is lightweight, promotes quiet operation, and is suitable for high speeds.
11206TN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior stiffness and enables the bearing to accommodate substantial radial dynamic loads (3510 lbf) and static loads (1046 lbf), as well as bidirectional axial loads.
- Optimized for High Speeds: The lightweight nylon (TN) cage reduces centrifugal forces, minimizes friction, and contributes to a high limiting speed of 6,700 rpm.
- Precision & Reliability: Manufactured from chrome steel with tight dimensional tolerances (e.g., bore diameter: -0.01mm to 0), this precision bearing ensures consistent performance and accuracy in demanding applications.
- Ready-to-Use: The bearing comes pre-lubricated, simplifying installation and providing immediate protection upon startup.
11206TN Bearing Typical Application Areas
This bearing is ideally suited for a range of industrial machinery and precision equipment, including:
- Machine Tool Spindles
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Precision Instruments and Medical Equipment
- Electric Motors
