Silicon Carbide SSiC Sleeve Bearing

Pressureless Sintered Silicon Carbide SSiC Sleeve  Bearing

Silicon Carbide sleeve bearing  is mainly used for shielding pump and magnetic pump for conveying medium, and can also be used for other. The utility model relates to a shaft sleeve for a silicon carbide sliding bearing, which is sleeve shaped. The utility model is characterized in that both ends of the inner side of the shaft sleeve are fixed mating surfaces 1, The middle part is a non fixed mating surface 2, and the middle part of the outer side of the shaft sleeve is a sliding mating surface 3, Both ends are non sliding mating surfaces 4. With automatic deformation with the increase of temperature

Compensate and absorb the difference of thermal expansion between pump shaft and silicon carbide sliding bearing sleeve. It does not have the advantage of large tensile force on the silicon carbide sleeve on the outside, Thus, the phenomenon that the silicon carbide sleeve is broken is overcome, and the application range of the pump is increased, The utility model improves the service life and overcomes the shortcomings of the prior art.

Silicon carbide seal ring  is an inorganic non-metallic material with high hardness, Low friction coefficient, strong oxidation resistance, good thermal stability, low coefficient of thermal expansion. High thermal conductivity, thermal shock resistance and chemical corrosion resistance,It can be used for mechanical equipment with various requirements, corrosion resistance and after years of unremitting efforts, engineers and technicians have greatly improved the performance of silicon carbide. Now, silicon carbide has become an important engineering material. Applied to machinery, Metallurgy, petrochemical, shipbuilding, equipment and other fields, such as mechanical seal friction pair sliding bearing, nozzle, cutting tool, etc.
