W 619/8-2RS1 Bearing Product Overview & Core Advantages
The W 619/8-2RS1 is a single row deep groove ball bearing designed for high performance in compact spaces. Engineered from stainless steel and featuring integral contact seals (2RS1), this precision bearing offers excellent resistance to corrosion and contamination. Its primary advantages include reliable operation under radial loads, a wide temperature range from -30°C to 120°C, and maintenance-free service due to its factory-pre-filled grease lubrication. This makes it an ideal, long-lasting solution for applications demanding high reliability and cleanliness.
W 619/8-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Stainless Steel bearing series |
| 619/8 | Bearing series and bore diameter (8 mm) |
| 2RS1 | Bearing with contact seals on both sides, providing superior protection against contaminants and moisture retention. |
W 619/8-2RS1 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from stainless steel (rings, balls, cage), this bearing provides excellent corrosion resistance, making it suitable for harsh environments and washdown applications.
- Superior Sealing: The 2RS1 contact seals effectively shield the internal components from dust, dirt, and moisture, while retaining the lubricant. This significantly enhances bearing life and ensures consistent performance.
- High-Speed Capability: With a limiting speed of 24,000 rpm, it is well-suited for high-speed applications. The optimized internal geometry and effective sealing contribute to stable operation at high rotational velocities.
- Maintenance-Free Operation: Pre-lubricated with high-quality grease, the bearing is ready for immediate use and requires no relubrication throughout its service life, reducing total cost of ownership.
- Precision & Load Capacity: Built to P0 tolerance class and a CN radial internal clearance, it offers reliable performance and can handle the specified radial dynamic and static load ratings.
W 619/8-2RS1 Bearing Typical Application Areas
This versatile miniature bearing is commonly specified in:
- Precision Instruments and medical devices
- Small electric motors and fans
- Food processing and packaging machinery (due to its stainless steel construction and seals)
- Office automation equipment (e.g., printers, scanners)
- Robotics and small gearboxes
