摘要： A cylindrical sintered material is placed in a cavity composed of die, a core disposed in the center of the die, and a pair of upper and lower punches provided within the die and compressed by the upper and lower punches. A gap is provided between an internal circumferential portion of the sintered material and an external circumferential portion of the core. Consequently, when the sintered material is compressed, plastic flow is produced at both ends of the sintered material so that an internal circumferential portions at corresponding portions protrude inward in a radius direction till the internal circumferential portions come into contact with the core, so that slide portions are formed.

摘要： A bearing comprising different materials having oil-filled pores in them has a relief space in the middle section which is not provided by machining. The materials are different, have different characteristics, and bear different portions of load the bearing supports, resulting in longer bearing life and reduced noise. Materials 1 and 2 are separately formed and sintered in such a way that material 1 has smaller pores in it and can support higher load, material 2 has larger pores in it and can support lower load, and an end portion of each material is stepped so that material 1 can be partially inserted into material 2 and a relief space is provided on the inner periphery of material 1. The materials 1 and 2 are then joined together into one piece, and the one piece is placed in a sizing die and pressed. The sized one piece is a strong one-piece bearing having an accurate inside diameter and good concentric alignment.
