2203ETN Bearing Product Overview & Core Advantages
The 2203ETN is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This sealed bearing excels at simultaneously handling combined radial and axial loads from both directions, making it ideal for compact designs. Its pre-lubricated construction and robust sealing ensure long service life with minimal maintenance, while the optimized internal geometry supports stable operation in demanding conditions.
2203ETN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 2203 | Standard bearing series designation indicating bore size and dimensions |
| E | Optimized internal design for enhanced load capacity and performance |
| TN | Nylon cage for reduced weight, lower friction, and superior high-speed capability |
2203ETN Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides exceptional rigidity and can sustain significant combined radial and axial loads from both directions, ensuring stable operation under varying load conditions.
High-Speed Performance: The lightweight nylon cage (TN) reduces centrifugal forces and friction, enabling higher rotational speeds while maintaining dimensional stability and alignment precision.
Sealed & Pre-Lubricated Design: Integrated sealing protects against contamination while factory-applied lubrication ensures consistent performance across the operating temperature range (-30° to 110°C), delivering maintenance-free operation.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances and CN radial internal clearance for consistent performance in precision applications.
