2203 Bearing Product Overview & Core Advantages
The 2203 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance in compact spaces. This sealed precision bearing is designed to accommodate combined loads, simultaneously handling significant radial forces and moderate axial loads from both directions. Its robust construction and pre-lubrication make it an ideal choice for high-reliability machinery where maintenance access is limited.
2203 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 2203 | Basic bearing designation indicating bearing dimensions (17mm bore, 40mm OD) |
| Sealed | Integrated contact seals providing superior contamination exclusion |
| CN Clearance | Normal radial internal clearance for general operating conditions |
| Nylon Cage | Lightweight polymer cage contributing to high-speed capability and smooth operation |
2203 Bearing Structural Features & Performance Benefits
Enhanced Rigidity: The double row design provides superior stiffness compared to single row bearings, minimizing deflection under load and ensuring precise shaft positioning.
Superior Load Capacity: Optimized raceway geometry and double row ball complement enable high radial dynamic load rating of 1989 lbf while effectively managing bidirectional axial loads.
High-Speed Performance: The lightweight nylon cage reduces centrifugal forces, while the factory-applied lubrication ensures reliable operation up to the limiting speed of 12,000 rpm.
Maintenance-Free Operation: Integrated seals retain lubricant and exclude contaminants, while the wide temperature range (-30° to 110°C) ensures consistent performance across various operating environments.
