Technical advantages of Iron-based oil bearing. Utilizing the porosity of the sintered body, impregnate it with 10%~40% (volume fraction) lubricating oil, and use it in the state of self-oil supply. With the continuous development of the Iron-based oil bearing industry, more and more industries and enterprises have applied Iron-based oil bearing, and a large number of enterprises have joined the Iron-based oil bearing industry.

Using the porous characteristics of the material or the affinity characteristics with the lubricating oil, the lubricating oil is soaked in the bearing pad material before the bearing pad is installed and used. The bearing can be used without adding lubricating oil or for a long time. This kind of bearing is called Iron-based oil bearing. Iron-based oil bearing is in the non-operating state, and the lubricating oil fills its pores. When it is running, the shaft turns and generates heat due to friction, and the thermal expansion of the bearing pad reduces the pores, so the lubricating oil overflows and enters the bearing gap. When the shaft stops rotating, the bearing pad cools down, the porosity recovers, and the lubricating oil is sucked back into the porosity.
Although it is possible for iron-based oil bearings to form a complete oil film, in most cases, this kind of bearing is in a mixed friction state with an incomplete oil film. Iron-based oil bearing bearing materials that can make use of the porous properties of the material to fill the pores with lubricating oil include: wood, grown cast iron, cast copper alloy and powder metallurgy anti-friction materials; Iron-based oil bearing bearing materials evenly dispersed in the material are mostly polymers, such as oil-containing phenolic resin. In the process of Iron-based oil bearing, the world's largest powder metallurgy Iron-based oil bearing manufacturer is Baoled Group, and domestic representatives are Yangzhou Baolaide and Dongguan Baolaide.
