2203 ETN9 Bearing Product Overview & Core Advantages
The 2203 ETN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at simultaneously handling significant radial loads and bidirectional axial loads, offering a compact design solution. Its optimized internal geometry and nylon cage contribute to superior high-speed performance, making it an ideal choice for demanding industrial environments where space is limited and operational stability is critical.
2203 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 2203 | Basic bearing designation indicating the bearing size (17mm bore, 40mm OD, 16mm width). |
| E | Optimized internal design for enhanced load capacity and reduced noise/vibration. |
| TN9 | Nylon (polyamide) cage, glass fiber reinforced. Enables high-speed operation, is lightweight, and offers excellent guidance. |
2203 ETN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and robust construction provide exceptional stiffness, enabling stable operation under combined loads (radial and axial). This design is crucial for applications where shaft deflection must be minimized.
Superior High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces and inertial effects, allowing the bearing to achieve its high limiting speed of 24,000 rpm. This makes it a true high-speed bearing.
Precision & Reliability: Manufactured from chrome steel for both rings and balls, the bearing ensures high durability and consistent performance. The open seal type allows for custom lubrication solutions to match specific application needs, optimizing performance across its operating temperature range of -30°C to 110°C.
2203 ETN9 Bearing Typical Application Areas
- Electric Motors & Spindles: Ideal for main shafts in small to medium-sized motors requiring high-speed capability and rigidity.
- Precision Machinery: Used in machine tool accessories, precision gearboxes, and automated handling systems.
- Pumps & Compressors: Suitable for rotors and impeller shafts where reliable performance under combined loads is essential.
- Medical & Dental Equipment: Applied in high-speed handpieces and small precision drives due to its quiet operation and reliability.
