2204 ETN9/W64 Bearing Product Overview & Core Advantages
The 2204 ETN9/W64 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open construction and is pre-lubricated, enabling it to handle significant combined loads including radial and bidirectional axial forces. Its compact design with a 20mm bore and 47mm outside diameter provides excellent space efficiency while maintaining high rigidity through its double row ball configuration. The bearing operates within a wide temperature range of -30° to 110°C, making it suitable for demanding industrial environments.

| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| E | Optimized internal design | Enhanced load capacity and performance |
| TN9 | Nylon cage, glass fiber reinforced | Excellent high-speed capability and reduced friction |
| W64 | Pre-lubricated with special grease | Extended service life and maintenance-free operation |
2204 ETN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row angular contact configuration provides superior stiffness and stability under combined loads, making it ideal for applications requiring precise positioning and minimal deflection.
Enhanced Load Capacity: With a radial dynamic load rating of 3780 lbf and radial static load rating of 934 lbf, this bearing effectively handles both radial and bidirectional axial loads simultaneously.
High-Speed Performance: The TN9 nylon cage with glass fiber reinforcement enables smooth operation at limiting speeds up to 20,000 rpm, while the optimized internal geometry reduces friction and heat generation.
Precision Engineering: Manufactured with chrome steel rings and balls, the bearing maintains dimensional stability with tight tolerances (bore: -0.01mm to 0, OD: -0.011mm to 0) for consistent performance in precision applications.
