2205 ETN9 Bearing Product Overview & Core Advantages
The 2205 ETN9 is a double row angular contact ball bearing engineered for applications demanding high precision and reliability. This metric bearing features an open design and is pre-lubricated, enabling it to accommodate significant combined loads—both radial and axial—simultaneously. Its compact dimensions (25 mm bore, 52 mm OD, 18 mm width) and robust construction make it an ideal solution for space-constrained assemblies requiring high rigidity and stable operation. The use of a nylon cage (ETN9) contributes to its suitability for high-speed applications, with a limiting speed of 18,000 rpm.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 2205 | Basic bearing designation indicating size series and bore diameter (25 mm). |
| E | Optimized internal design for enhanced load capacity and performance. |
| TN9 | Nylon cage, glass fiber reinforced, suitable for high speeds and offering reduced friction. |
2205 ETN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior rigidity and enables the bearing to handle substantial radial loads (dynamic rating: 3780 lbf) and axial loads from both directions simultaneously, making it ideal for applications with complex loading conditions.
High-Speed Performance: The lightweight nylon cage (TN9) minimizes centrifugal forces and ensures smooth operation at high rotational speeds, up to the limiting speed of 18,000 rpm.
Precision & Reliability: Manufactured from chrome steel for both rings and balls, the bearing offers high dimensional stability and wear resistance. The tight bore diameter tolerance (-0.01mm to 0) ensures precise fits in demanding applications.
Pre-Lubricated & Ready-to-Use: The bearing is supplied with lubricant, facilitating immediate installation and initial operation within the specified temperature range of -30°C to 110°C.
