必要があり、生産性に問題があった。Problem to be Solved by the Invention 1 However, silicon carbide sintered viscous material is usually machined into the desired shape using a grinder, but if a large cutting angle is used during machining, cracks may occur and a good finish may not be obtained. Since it is difficult to obtain a surface, there are workability problems such as having to make the cutting depth small during processing.Furthermore, carbon sintered bodies need to be fired for at least one month to obtain a graphitized product. There was a problem with productivity.

意が必要となる欠点があった。Bearings made of carbon or silicon carbide may crack when press-fitted into equipment housings such as pumps, so they should be bonded to metal parts by shrink-fitting, etc. before being press-fitted into equipment housings. However, there are disadvantages in that the assembly work is complicated and the workability is poor, and that care must be taken when handling such bearings in packaging and transportation operations when the bearing is assembled into a lotus shell.

効である。[Carbonized 1] The crystallinity of the carbonized fiber is 15% or more, preferably 20% or more, and more preferably 30% or more. According to experiments conducted by the present inventors, the relationship between the degree of carbonization (crystallinity of J fibers and friction and wear characteristics) increases as the degree of crystallinity increases (in particular, by increasing the degree of crystallinity) The abrasive resistance of silicon carbide fibers is improved.Therefore, it is effective to use fibers with a high degree of crystallinity, for example, in applications such as submersible pumps where the inflow of earth and sand is inevitable.
