2203S Bearing Product Overview & Core Advantages
The 2203S is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loading conditions. This sealed bearing features a compact design with a 17 mm bore and is pre-lubricated for immediate use. Its primary advantage lies in its ability to simultaneously support substantial radial loads and bidirectional axial loads, making it an ideal precision bearing for high-reliability machinery where space is at a premium.
2203S Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 2203 | Standard bearing series designation indicating the bearing dimensions (17 mm bore, 40 mm OD, 16 mm width). |
| S | Denotes the bearing is sealed on both sides, providing superior protection against contamination and retaining lubricant. |
2203S Bearing Structural Features & Performance Benefits
