W 628/7 R-2RS1 Bearing Product Overview & Core Advantages
The W 628/7 R-2RS1 is a single row deep groove ball bearing designed for high reliability in compact spaces. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1) with pre-applied grease lubrication, making it a maintenance-free solution ideal for applications requiring protection from contaminants. This bearing is engineered to handle primarily radial loads and operates efficiently across a wide temperature range.

W 628/7 R-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RS1 contact seals effectively shield the bearing interior from dust, moisture, and other contaminants, significantly extending service life and enabling use in harsh environments.
- Flanged Design: The integral flange on the outer ring (R) simplifies bearing mounting and alignment within a housing, reducing assembly time and cost.
- Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel, providing superior corrosion resistance and suitability for washdown or chemical exposure.
- Ready-to-Use Lubrication: Pre-greased from the factory, the bearing is maintenance-free and immediately operational, ideal for sealed-for-life applications.
