Brass Bushing Motor Components

Self-lubricating sintered bearings deliver high performance under load and offer exceptional wear properties. The porosity of bearings produced through the conventional powdered metal process makes oil impregnation possible, eliminating the need for a supplemental lubrication system. This lifelong lubrication makes sintered bearings a versatile alternative to costly roller bearings.
