[0006] The composite ceramic steel bracket O-type ball includes a skeleton and composite ceramics. The skeleton can be processed according to the needs. The processed skeleton is fixed in the mold, and then the composite ceramic is quickly gel-formed. Because the O-type ball has a skeleton, the stress bearing capacity of the O-type ball is improved, and the stress distribution is more uniform, the service life and safety are improved, and the mechanical strength of the product is greatly improved. The entire product is coated with a composite ceramic material. The composite ceramic has high wear resistance, high strength, corrosion resistance and a small thermal expansion coefficient. It is further supported by the skeleton, which greatly increases the strength of the product.
