11206 TN9 Bearing Product Overview & Core Advantages
The 11206 TN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at simultaneously handling combined loads, including significant radial loads and moderate axial loads in both directions. Its compact bearing dimensions (30mm bore, 62mm OD, 48mm width) and robust construction make it ideal for space-constrained, high-performance mechanical systems. The open design, combined with a nylon cage (TN9) and factory-applied lubrication, enables smooth operation at elevated speeds while maintaining dimensional stability.
11206 TN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 11206 | Basic designation indicating a double row angular contact ball bearing with 30mm bore diameter |
| TN9 | Nylon cage, glass fiber reinforced, providing excellent high-speed performance and reduced friction |
11206 TN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to handle combined loads effectively. With a dynamic load rating of 3510 lbf and static load rating of 1046 lbf, it offers reliable performance in demanding applications.
High-Speed Performance: The TN9 nylon cage ensures optimal performance at high rotational speeds, contributing to the bearing's limiting speed of 6,700 rpm. The cage's lightweight construction reduces centrifugal forces and maintains stability during rapid acceleration.
Precision Engineering: Manufactured with tight dimensional tolerances (bore: -0.01mm to 0, OD: -0.013mm to 0) and constructed from chrome steel for both rings and balls, this bearing delivers consistent accuracy and long service life in precision applications.
Temperature Compatibility: Operating temperature range of -30°C to 110°C ensures reliable performance across various environmental conditions, while the factory-applied lubrication provides immediate readiness for installation.
