| 摘要 |
The improved slide bearing assembly comprises at least a shaft (10) and a bush (9) that is formed of a porous iron-base sintered material. The bush (9) is impregnated with a lubricant oil having a viscosity of 2.4 to 15 cm<2>/s. The bearing assembly can be operated in slow- and high-pressure applications without oil refillings for a prolonged period of at least several years. The shaft is preferably formed of an iron or a steel member that have been subjected to a treatment of surface modification. The slide bearing assembly is preferably used in such an environment that the working pressure applied to the sliding surface is at least 600 bar and that the sliding speed is in the range 2 - 5 cm/sec. <IMAGE> |
