Material Features:

FU-1 sintered bronze bushing powder is mold pressed under high pressure and then sintered under high temperature, and oil is soaked into the homogeneously spreaded tiny pores of the metal under vacuum. FU bearing can withstand dry condition in medium speed and low load for short time. Moreover it is cheap and stable in dimension. This is widely used in domestic electric and electronic machines, electric tools, textile machines, chemical engineering machines, automobiles and official business machines.

FU-2 sintered iron power bearings can protect shaft with oil. They're anti- friction same as bronze power bearings under low load. They're widely used in textile machines, electric tools and absorbers of auto and motorcycle. When being static, they can be acted as orientation bushing.

FU-3 sintered bronze-iron bushing have the advantages of FU-1 and FU-2. The proportion of iron and bronze can be designed by customers' different requests. It can reduce cost but satisfy customers.
