The base metal is aimed for high loads and the solid lubricant makes it possible to use B50 bearings without additional lubrication. B50 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. Both the base material and the solid lubricant can be fitted to special needs to achieve the most suitable solution for the application in question.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Benefits” tab_id=”1707219042709-07cd6681-9743″][vc_column_text]- Extremely high load capacity
