11207 TN9 Bearing Product Overview & Core Advantages
The 11207 TN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric system bearing features an open design without seals, allowing for optimal lubrication access. Its double row construction enables it to accommodate significant combined loads—both radial and bidirectional axial loads—while maintaining high rigidity. Manufactured from chrome steel with a nylon cage, it delivers excellent performance in demanding environments.
11207 TN9 Bearing Model Code Explained, Specifications & Naming Convention

|---|---|
| 11207 | Basic bearing designation indicating double row angular contact ball bearing with 35mm bore diameter |
| TN9 | Nylon cage, glass fiber reinforced, suitable for high-speed applications |
11207 TN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness compared to single row bearings, making it ideal for applications requiring precise shaft positioning. With a radial dynamic load rating of 4275 lbf and radial static load rating of 1350 lbf, this bearing effectively handles combined loads in demanding operating conditions.
High-Speed Performance: The TN9 nylon cage contributes to excellent high-speed capabilities, with a limiting speed of 5,600 rpm. This polymer cage offers reduced friction, lower weight, and better acceleration characteristics compared to metal cages.
Precision Engineering: Manufactured with tight dimensional tolerances (bore: -0.012mm to 0, outside diameter: -0.013mm to 0), this bearing ensures precise fit and reliable performance in precision applications.
Material Excellence: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability. The bearing operates effectively within a temperature range of -30°C to 110°C.
