With the same production process and use conditions of FB090, it is based on the bronze substrate. The graphite-based solid lubricant is filled in its rhombus-shaped oil holes, so that the product could enjoy lower friction coefficient at the starting stage and in-use stage. Here, the good working condition could be still kept even though lubricating is unavailable within the short time. Therefore, it is widely used in the high load and medium speed positions such as engineering machinery, gearbox drive components, motor vehicle clutch as well as the rotary position for outdoor high-altitude facility.
