W 61809-2RS1 Bearing Product Overview & Core Advantages
The W 61809-2RS1 is a single row deep groove ball bearing designed for high-performance applications requiring reliability and precision. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions. The integral contact seals (2RS1) and pre-applied grease lubrication ensure long-term, maintenance-free operation, making it ideal for applications demanding high reliability and a compact design.

W 61809-2RS1 Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components (rings, balls, cage) are made from stainless steel, providing excellent resistance to corrosion and enabling use in harsh environments.
- High Load Capacity: The deep groove raceway and single row design are optimized to carry high radial dynamic load ratings and moderate bidirectional axial loads.
- Maintenance-Free Operation: The 2RS1 contact seals effectively shield the bearing interior from dust and moisture while retaining the pre-filled grease, resulting in a long service life without re-lubrication.
- Precision & Stability: Manufactured to P0 tolerance class with a standard CN radial internal clearance, ensuring consistent performance, smooth operation, and precise running accuracy.
