BWG-bearings with or without flange are made of casted bronze material with special solid lubricant embedded.
The base metal is aimed for high loads and the solid lubricant makes it possible to use BWG-bearings without additional lubrication. BWG-bearings show excellent performance without lubrication under conditions of low speeds and extreme high or low temperatures. The lubrication reservoirs are dispersed in a special way over the bearing surface, therefore the whole bearing surface is lubricated when the movement occurs. These lubrication reservoirs cover about 25-30% of the sliding surface.
