ABSTRACT:
A journal assembled to a rotary shaft has its outer portion made of solid phase sintered alloy having 10% to 30% by volume of sintering pores inpregnated with lubricating oil and its inner portion is made of a liquid phase sintered alloy being sinterable at the same temperature as the solid phase sintered alloy. The outer portion is wear-resistant and well lubricable due to the oil impregnated therein. The inner portion is tightly secured to both the outer portion and the rotary shaft because the liquid phase sintered alloy is metallurgically diffusion-bonded to both the solid phase sintered alloy and the rotary shaft.
