Engineered for enclosed mechanical environments where external lubrication is continuously supplied, the 6217 Open is a premium single-row deep groove ball bearing designed without shields or seals. This "open" architecture allows for the free, unrestricted circulation of oil or grease directly through the rolling elements, making it the superior choice for oil-bath lubrication systems. Featuring standardized metric dimensions of an 85 mm bore, 150 mm outer diameter, and 28 mm width, this bearing delivers exceptionally smooth, high-speed rotation and robust load-bearing capabilities for internal machinery components.
