DALON SINTERED BRONZE BUSHING INTRODUCTION:

DALON self-lubricating Powder Metallurgy Bushingg 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 Powder Metallurgy Bushing to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.
