They are typically impregnated with Teflon so that they don't need additional lube. They are not inherently "sealed" but they tolerate dirt better than ball bearings. Ball bearings can't tolerate dirt very well because of tight clearances and they don't last long if the lubricant gets washed out. But if you keep ball bearings clean and lubed they will out-last a sleeve bearing.
