11206 TN9/W64 Bearing Product Overview & Core Advantages
The 11206 TN9/W64 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 capable of accommodating combined radial loads. Its compact double-row construction provides superior stability and is engineered for high-reliability applications where space is at a premium and performance is critical.
11206 TN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 11206 | Basic bearing designation indicating a double row angular contact ball bearing with a 30mm bore. |
| TN9 | Indicates a nylon cage, which contributes to lower friction, reduced weight, and suitability for high-speed operation. |
| W64 | Specifies the bearing is pre-lubricated with a specific grease suitable for the designated temperature range. |
11206 TN9/W64 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides significantly greater radial stiffness compared to single row bearings, enabling it to handle substantial radial dynamic loads (3510 lbf) and radial static loads (1046 lbf) with minimal deflection.
- Optimized High-Speed Performance: The lightweight nylon cage (TN9) ensures smooth operation and lower centrifugal forces, allowing for a high limiting speed of 6,700 rpm.
- Precision & Reliability: Manufactured from chrome steel for both rings and balls, this bearing ensures high durability and long service life. The standard CN radial internal clearance is suitable for a wide range of common industrial applications.
- Ready-to-Install: The bearing is pre-lubricated, simplifying installation and providing immediate protection upon startup.
11206 TN9/W64 Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for demanding applications across various industries, including:
- Precision Machine Tool Spindles
- Industrial Gearboxes
- Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
