Model Code Breakdown
| Model Segment | Description | Technical Meaning |
|---|---|---|
| W | Stainless Steel Bearing | Indicates the bearing rings, balls, and cage are made from stainless steel for enhanced corrosion resistance. |
| 61804 | Bore Size & Series | Denotes the "618" series (extra thin section) with a 20 mm bore diameter. |
| 2RS1 | Sealing | Signifies contact seals on both sides, providing effective protection against contaminants and retaining lubricant. |
W 61804-2RS1 Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and cage, are manufactured from stainless steel, ensuring excellent corrosion resistance and suitability for harsh environments.
- Effective Sealing with 2RS1: The double-sided contact seals effectively shield the bearing interior from dust, moisture, and other contaminants, while also retaining the pre-applied grease lubrication for long-term, maintenance-free operation.
- High-Speed Capability: The optimized design and effective lubrication contribute to a high limiting speed of 13,000 rpm, making it suitable for high-speed applications.
- Precision and Reliability: Manufactured to P0 tolerance class and standard CN radial internal clearance, this bearing offers consistent performance and smooth running for precision equipment.
W 61804-2RS1 Bearing Typical Application Areas
- Food and Beverage Processing Equipment (due to stainless steel construction and sealing)
- Medical and Dental Devices
- Precision Instruments and Optical Devices
- Small Electric Motors and Gearboxes
- Pumps and Compressors for corrosive or clean environments
