11209 TN9 Bearing Product Overview & Core Advantages
The 11209 TN9 is a double row angular contact ball bearing designed for applications requiring exceptional rigidity and the ability to handle combined loads. This precision bearing efficiently supports substantial radial loads and bidirectional axial loads simultaneously, making it ideal for high-reliability machinery. Its compact design, featuring two rows of balls, provides a robust solution in a minimal footprint. Manufactured with high-grade chrome steel and a nylon cage (TN9), it is optimized for smooth operation and extended service life.
11209 TN9 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 11209 | The basic bearing designation, indicating a metric double row angular contact ball bearing with a 45 mm bore, 85 mm OD, and 58 mm width. |
| TN9 | Indicates the cage type: a molded nylon cage, designated as TN9. This cage material is lightweight, reduces friction, and is excellent for high-speed operation. |
11209 TN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design significantly increases the bearing's rigidity and its capacity to handle combined radial and axial loads from both directions, providing stable and precise shaft support.
High-Speed Performance: The lightweight nylon TN9 cage ensures excellent guidance of the balls with minimal friction and inertia, contributing directly to the bearing's high limiting speed of 4,500 rpm.
Precision & Durability: Manufactured from high-carbon chrome steel, the bearing rings and balls offer high wear resistance and durability. The open seal type allows for easy re-lubrication to maintain optimal performance.
Operational Readiness: The bearing comes pre-lubricated, ensuring immediate operational readiness and smooth running-in period.
