2204 E-2RS1TN9/GFJ Bearing Product Overview & Core Advantages
The 2204 E-2RS1TN9/GFJ is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This sealed bearing excels at simultaneously handling combined loads, including significant radial loads and bidirectional axial loads. Its compact design, featuring a 20mm bore and 47mm outside diameter, makes it ideal for space-constrained, high-rigidity applications. The bearing comes pre-lubricated for long service life and is built for demanding operational environments.
2204 E-2RS1TN9/GFJ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 2204 | Basic bearing designation (20mm bore, 47mm OD) |
| E | Optimized internal design |
| 2RS1 | Contact seals on both sides for superior protection |
| TN9 | Polyamide (nylon) cage, glass fiber reinforced |
| GFJ | Specific high-performance grease filling |
2204 E-2RS1TN9/GFJ Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides exceptional stiffness, enabling stable support for shafts under combined loads. This construction allows the bearing to handle both radial loads (dynamic rating: 2858 lbf) and bidirectional axial loads effectively.
Enhanced Sealing & Lubrication: The 2RS1 contact seals offer superior protection against contaminants while retaining lubricant. Combined with the special GFJ grease, this ensures reliable operation across the specified temperature range (-30° to 110°C) and contributes to the bearing's maintenance-free characteristics.
Optimized High-Speed Performance: The TN9 polyamide cage is lightweight and durable, reducing centrifugal forces and enabling smooth operation at higher speeds (limiting speed: 10,000 rpm). The precise bearing dimensions and optimized internal geometry further support stable high-speed performance.
2204 E-2RS1TN9/GFJ Bearing Typical Application Areas
This precision bearing is particularly suited for applications requiring compact design, high rigidity, and reliable sealed operation:
- Electric motors and generators
- Industrial gearboxes and transmissions
- Pumps and compressors
- Material handling equipment
- Agricultural machinery
- Small industrial fans and blowers
