Oil Apertures Wrapped Bronze Bearing For Engineering Machines
It is made of Tin-bronze CuSn8P. Its surface is punched with oil apertures by certain angle and density. Therefore, it is easier to form an oil film when the bush works. Moreover, It has good anti-fatigue and load, anti-erosion and abrasion capacity. The products are widely applied in conditions of heavier load but low running velocity, such as on agricultural, building and engineering machines, etc.
