Graphite Bushings Impregnated
DALON SINTERED BRONZE BUSHING INTRODUCTION: DALON self-lubricating Graphite Bushings Impregnated are manufactured of pressed copper and tin powders by sintered technology and impregnated with lubricating oil and high porosity (20-25% in volume). The oil contained in the porosity provides a constant lubrication between bearing and shaft, the system does not need any additional external lubricant, allows this type of sintered bronze bushing to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.
