11210 TN9 Bearing Product Overview & Core Advantages
The 11210 TN9 is a double row angular contact ball bearing designed for applications requiring high load capacity and rigidity. This precision bearing excels at handling combined loads, simultaneously supporting significant radial loads and axial loads in both directions. Its compact design, featuring two rows of balls, provides a robust solution for high-reliability machinery. The bearing comes pre-lubricated and utilizes a Nylon cage (TN9 designation), contributing to its suitability for high-speed operation and smooth performance.
11210 TN9 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Description | Technical Implication |
|---|---|---|
| 11210 | Basic Bearing Code | Defines the bearing dimensions: 50mm bore, 90mm OD, 58mm width. |
| TN9 | Cage Type | Indicates a glass fiber reinforced Nylon 66 cage. This design reduces friction, allows for higher speeds, and is suitable for a wide temperature range. |
11210 TN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction significantly increases the bearing's rigidity and its ability to carry combined loads (radial and axial), making it ideal for applications with complex force scenarios.
