W 61800-2RS1 Bearing Product Overview & Core Advantages
The W 61800-2RS1 is a metric miniature deep groove ball bearing designed for compact applications requiring high precision and reliability. This sealed single row bearing excels at handling radial loads and is constructed entirely from stainless steel for superior corrosion resistance. Its key advantages include a compact design, maintenance-free operation due to integrated seals and pre-lubrication, and consistent performance across a wide temperature range from -30°C to 120°C, making it an ideal choice for demanding and space-constrained environments.
Model Code In-Depth Analysis
| Code Segment | Technical Meaning |
|---|---|
| W | Stainless Steel Bearing |
| 61800 | Series designation for miniature deep groove ball bearings with a 10mm bore. |
| 2RS1 | Features contact seals on both sides. The "RS1" suffix indicates low-friction, nitrile rubber (NBR) seals that provide excellent protection against contamination and moisture retention of grease. |
W 61800-2RS1 Bearing Structural Features & Performance Benefits
- Compact & Robust Design: The single row construction with a small cross-section (5mm width) allows for integration into highly compact assemblies without sacrificing performance.
- Corrosion Resistance: Manufactured entirely from stainless steel (rings, balls, and cage), this bearing is inherently resistant to rust and corrosion, suitable for harsh environments and washdown applications.
- Maintenance-Free Operation: The integral 2RS1 contact seals effectively shield the bearing interior from contaminants and retain the pre-applied grease lubrication, enabling long service life without re-lubrication.
- Precision & Speed: Built to P0 tolerance class and CN radial internal clearance, it ensures smooth, quiet operation and is capable of running at limiting speeds up to 22,000 rpm.
W 61800-2RS1 Bearing Typical Application Areas
This bearing is ideally suited for applications where small size, corrosion resistance, and reliability are critical. Common uses include:
- Precision Instruments and optical devices
- Small Electric Motors and gearboxes
- Medical and Dental Handpieces
- Food Processing and Packaging Equipment
- Office Automation Equipment (e.g., printers, scanners)
- Robotics and RC Models
