2203 E-2RS1TN9 Bearing Product Overview & Core Advantages
The 2203 E-2RS1TN9 is a double row angular contact ball bearing engineered for applications requiring high precision and reliability. This sealed bearing is designed to accommodate combined loads, simultaneously handling significant radial loads and axial loads in both directions. Its compact design and robust construction make it an ideal solution for space-constrained assemblies demanding high rigidity and long-term performance. Pre-lubricated and sealed for life, it offers a maintenance-free operational solution.
2203 E-2RS1TN9 Bearing Model Code Explained, Specifications & Naming Convention
| 2203 | Basic bearing series designation, indicating a metric double row angular contact ball bearing with a 17mm bore diameter. |
| E | Optimized internal design, typically featuring reinforced construction and increased load capacity. |
| 2RS1 | Features contact seals on both sides (RS1 type), providing superior protection against contaminants and effective grease retention. |
| TN9 | Indicates a glass fiber reinforced polyamide (nylon) cage. This cage design is lightweight and contributes to smooth operation, low friction, and suitability for high-speed applications. |
2203 E-2RS1TN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to support substantial combined loads with minimal deflection, ensuring precise shaft positioning.
Optimized High-Speed Performance: The lightweight and robust TN9 nylon cage minimizes centrifugal forces and ensures stable operation at the bearing's limiting speed of 12,000 rpm. The optimized internal geometry further enhances high-speed capability.
Maintenance-Free & Long Service Life: The integral 2RS1 contact seals effectively shield the bearing internals from moisture and particulate contaminants while retaining the factory-applied high-quality lubricant. This sealed-for-life construction eliminates the need for re-lubrication.
Precision Engineering: Manufactured from high-grade chrome steel and adhering to strict dimensional tolerances, this bearing ensures consistent performance, low noise, and smooth running in demanding applications.
