2203-2RSTN Bearing Product Overview & Core Advantages
The 2203-2RSTN is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing excels at simultaneously handling combined loads, including significant radial loads and bidirectional axial loads. Its compact bearing dimensions (17mm bore, 40mm OD, 16mm width) and sealed construction make it ideal for applications requiring high reliability, rigidity, and minimal maintenance. The pre-lubricated design ensures immediate operation and long service life.
2203-2RSTN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| 2RS | Double-sided contact seals (Rubber). Provides excellent protection against contamination and retains lubricant. |
| TN | Nylon (Polyamide) cage. Contributes to quiet operation, lower friction, and is suitable for high-speed applications. |
2203-2RSTN Bearing Structural Features & Performance Benefits
- High Rigidity: The double row ball construction provides superior radial and axial stiffness, ensuring stable operation under combined loads.
- Exceptional Load Capacity: Engineered to handle substantial radial loads and bidirectional axial loads simultaneously, making it versatile for complex loading conditions.
- Optimized for Speed: The lightweight TN cage reduces centrifugal forces, enabling a high limiting speed of 12,000 rpm.
- Maintenance-Free Operation: The integral 2RS seals effectively shield the bearing from contaminants and retain the factory-applied lubricant, resulting in a long, maintenance-free service life.
- Precision Engineering: Manufactured from Chrome Steel with tight dimensional tolerances for consistent, reliable performance in precision assemblies.
