Model Code Breakdown
| Prefix / Suffix | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing. |
| 61806 | The basic bearing designation, indicating a single row deep groove ball bearing with a 30 mm bore, 42 mm OD, and 7 mm width. |
| -2RZ | Signifies that the bearing is fitted with non-contact seals on both sides. The "RZ" suffix indicates low-friction seals, offering effective protection against contaminants with minimal impact on the limiting speed. |
W 61806-2RZ Bearing Structural Features & Performance Benefits
- Compact and Robust Design: The single row deep groove raceway and compact bearing dimensions (30x42x7 mm) provide a space-saving solution without compromising on load capacity.
- High Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, and cage), this bearing is ideal for applications exposed to moisture, chemicals, or washdown environments.
- Sealed and Pre-Lubricated: The 2RZ non-contact seals effectively shield the internal components from dust and moisture while retaining the factory-applied grease lubrication. This contributes to a maintenance-free and long service life.
- Precision Performance: Manufactured to P0 tolerance class and standard CN radial internal clearance, it ensures smooth and quiet operation, suitable for high-speed applications up to 17,000 rpm.
