2204 E-2RS1TN9/W64 Bearing Product Overview & Core Advantages
The 2204 E-2RS1TN9/W64 is a Double Row Angular Contact Ball Bearing engineered for applications demanding high precision and reliability. This sealed bearing is designed to accommodate significant combined loads, simultaneously supporting substantial radial loads and axial loads in both directions. Its compact design, featuring a 20 mm bore and 47 mm outside diameter, offers a space-saving solution without compromising performance. Pre-lubricated with a specialized grease, it ensures long-term, maintenance-free operation within a wide temperature range, making it an ideal precision bearing for robust and high-rigidity support systems.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| 2204 | Basic Bearing Number | Denotes a metric series double row angular contact ball bearing with a 20mm bore and 47mm OD. |
| E | Optimized Internal Design | Indicates an enhanced internal geometry for increased load capacity and performance. |
| 2RS1 | Sealing Type | Features contact seals on both sides, providing superior protection against contaminants and effective grease retention. |
| TN9 | Cage Type | A Nylon (Polyamide) cage, which is lightweight and contributes to smooth operation, lower friction, and higher limiting speeds. |
| W64 | Lubrication | Specifies a high-performance lithium-based grease, suitable for the stated temperature range and offering long-lasting lubrication. |
2204 E-2RS1TN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and optimized internal "E" design provide exceptional high rigidity, making the bearing highly resistant to operational deflection. This construction enables it to handle significant combined loads (radial and bidirectional axial) effectively, with a dynamic load rating of 2858 lbf.
High-Speed Performance: The lightweight TN9 Nylon cage reduces centrifugal forces and minimizes friction, allowing for a high limiting speed of 10,000 rpm. This makes it a capable high-speed bearing for demanding applications.
Maintenance-Free & Long Service Life: The integral 2RS1 contact seals effectively shield the bearing internals from dust, moisture, and other contaminants while retaining the pre-applied W64 grease. This sealed and pre-lubricated configuration ensures reliable, maintenance-free operation over an extended service life.
Precision & Reliability: Manufactured from chrome steel for both rings and balls, and adhering to strict dimensional tolerances, this bearing delivers consistent precision and reliable performance in critical machinery.
