W 61902 R-2Z Bearing Product Overview & Core Advantages
The W 61902 R-2Z is a single row deep groove ball bearing designed for high performance and reliability in compact spaces. Engineered from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads while its shielded design and pre-lubrication ensure long-term, maintenance-free operation. This makes it an ideal precision bearing for applications demanding cleanliness, durability, and consistent performance within a wide temperature range.

W 61902 R-2Z Bearing Structural Features & Performance Benefits
- Compact & Robust Design: The single row deep groove geometry and integral flange (30.5mm diameter) provide secure and precise mounting, simplifying assembly and enhancing system rigidity.
- High Corrosion Resistance: All components, including rings, balls, and cage, are manufactured from stainless steel, making the bearing suitable for harsh environments and washdown applications.
- Maintenance-Free Operation: The 2Z shields effectively retain the factory-applied grease lubrication and exclude contaminants, ensuring long service life without re-lubrication.
- Optimized Performance: With a limiting speed of 28,000 rpm and a CN radial internal clearance, the bearing is well-suited for high-speed applications requiring smooth and quiet operation.
