11208 TN9 Bearing Product Overview & Core Advantages
The 11208 TN9 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. This metric bearing features an open design, enabling it to accommodate significant radial loads while also handling axial loads in both directions. Its compact construction, utilizing a nylon cage and premium chrome steel components, makes it an ideal choice for high-precision machinery where space constraints and operational reliability are critical. The pre-lubricated design ensures immediate readiness for service, contributing to its status as a high-performance precision bearing.
11208 TN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 11208 | Standard bearing designation indicating a double row angular contact ball bearing with a 40mm bore. | Defines core bearing dimensions and type. |
| TN9 | Specifies a glass fiber reinforced polyamide (nylon) cage, snap-type design. | Contributes to lower friction, quieter operation, and suitability for high-speed applications. |
11208 TN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness compared to single row bearings, offering stable support against combined loads and moment loads. This makes it exceptionally durable in applications with significant stress.
Optimized High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces and reduces friction, enabling a high limiting speed of 5,000 rpm. This is critical for maintaining precision and efficiency in high-speed machinery.
Precision Engineering & Material Quality: Manufactured from high-grade chrome steel for both rings and balls, the bearing ensures excellent wear resistance and long service life. The tight dimensional tolerances on the bore diameter, outside diameter, and width guarantee consistent performance and ease of installation.
Ready-to-Use Lubrication: The bearing is supplied pre-lubricated, facilitating immediate installation and initial operation, reducing maintenance downtime.
11208 TN9 Bearing Typical Application Areas
- Machine Tool Spindles: Where high rigidity and running accuracy are paramount.
- Industrial Gearboxes: For supporting gears and shafts under heavy combined loads.
- Pumps and Compressors: Ideal for handling radial and axial forces in rotating assemblies.
- Material Handling Equipment: Providing robust support in conveyor pulleys and rollers.
- Precision Agricultural and Construction Machinery: For high-load, high-reliability applications.
