W 61804-2RS1/R799 Bearing Product Overview & Core Advantages
The W 61804-2RS1/R799 is a single row deep groove ball bearing designed for precision and reliability in compact spaces. Engineered from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle primarily radial loads efficiently, while the sealed design (2RS1) ensures protection from contaminants and retains lubrication, making it suitable for applications demanding long-term performance with minimal maintenance. This bearing is characterized by its ABEC 1 precision class and compact cross-section, providing a robust solution for high-speed operation up to 13,000 rpm.

W 61804-2RS1/R799 Bearing Structural Features & Performance Benefits
- Corrosion Resistance & Cleanliness: The use of stainless steel for rings and balls makes this bearing ideal for applications exposed to moisture, chemicals, or requiring washdown, such as in food and beverage or medical equipment.
- Robust Sealing: The 2RS1 contact seals effectively shield the bearing interior from dust, dirt, and moisture, while also retaining the pre-applied R799 grease. This significantly extends service life and enables maintenance-free operation in many environments.
- High-Speed Capability: The single row deep groove design, combined with precision manufacturing (ABEC 1) and optimized grease lubrication (R799), allows for a high limiting speed of 13,000 rpm.
- Precision & Load Capacity: Manufactured to ABEC 1 (ISO P0) tolerance standards with standard CN radial internal clearance, this bearing ensures smooth, quiet, and reliable operation under its specified radial dynamic load rating of 701 lbf.
