Its key advantage lies in its ability to handle radial loads effectively while providing robust protection against contamination, making it ideal for applications demanding long service life and consistent performance in challenging environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| W 604 | Basic bearing designation for a single row deep groove ball bearing with a 4 mm bore. |
| 2RS1 | Bearing is fitted with contact seals on both sides, providing superior protection against dust and moisture ingress. |
| W64 | Indicates the bearing is filled with Solid Oil lubrication, ensuring a long-lasting, maintenance-free lubricating film. |
W 604-2RS1/W64 Bearing Structural Features & Performance Benefits
Compact and Robust Design: The single row construction with a 4 mm width offers a space-saving solution without compromising on load capacity. The stainless steel rings and balls provide inherent corrosion resistance, extending bearing life.
Sealed and Lubricated for Life: The 2RS1 contact seals effectively shield the internal components from contaminants. Combined with the integrated Solid Oil (W64), this design eliminates the need for re-lubrication, offering a maintenance-free solution across its entire operating temperature range of -30°C to 120°C.
Precision and Speed: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, this bearing ensures smooth and quiet operation, suitable for applications with a limiting speed of 80,000 rpm.
