SF-2-type material has its special wear patterns, as shown in Figure 4, when installed in the case of grease, in the R phase of a very small amount of wear and tear. After the R phase time loses the boundary oil lubrication condition, the wear begins to aggravate. At this point refueling, can maintain no significant wear and tear, and its life can be greatly extended. The advantage of the SF-2 material is therefore that it is necessary to refuel once during the inter-R phase, which is significantly longer than the interval between the other materials, in particular the metallic material. About five times.
When assembled with grease (such as lithium grease or silicone grease, etc.), SF-2 bushing life, with the work of the PV value in which the upper and lower. The fuel consumption of the SF-2 bushings is about half that of the service life. For example, when PV = 2.5MPam / s, requiring every 100 hours must be refueling maintenance once. termination. As shown in the figure III curve.
