Silicon carbide shaft sleeve is designed to reduce friction and wear when the shaft movement, the basic use and bearing is the same. Reactive sintered silicon carbide bushing is synthesized by using silicon carbide and carbon at high temperature. It has corrosion resistance, wear resistance and high temperature resistance. It is suitable for mechanical products with high precision and sealing requirements, such as high pressure pumps and magnetic pumps.

Non-pressure sintered silicon carbide sleeve is made of 0.5 micron ultrafine powder as raw material, nano silicon carbide, with high purity, small particle size distribution range, high specific surface area, stable chemical properties, high thermal conductivity (165W/MK), small thermal expansion coefficient, high hardness. Its Mohr hardness of 9.5, microhardness of 2840-3320kg/mm2, between corundum and diamond, mechanical strength is higher than corundum. Nano silicon carbide has excellent thermal conductivity, or a semiconductor, can resist oxidation at high temperature; Nano silicon carbide wear resistance, high temperature resistance, corrosion resistance, acid and alkali solvent resistance, widely used in coating, paint and other fields, increase wear resistance.

Edge, cloth (hangzhou) mechanical seal co., LTD., fully using the excellent characteristics of silicon carbide ultrafine powder professional production produced the pressureless sintering of silicon carbide shaft sleeve with high strength, high temperature resistant, high hardness, high wear resistance, corrosion resistance, oxidation resistance, thermal shock resistance, good thermal shock resistance, good thermal conductivity and thermal efficiency higher basic performance and main characteristics. The non-pressure sintered silicon carbide bushing produced by the use of advanced production equipment is more resistant to wear, high temperature and corrosion than the reaction sintered silicon carbide bushing, and the working environment can reach up to 1650℃. Not only can be applied to petroleum, chemical, automobile, military, paper, but also can be applied to food, pharmaceutical, nuclear industry and other industries, generally applicable to: precision, sealing requirements of mechanical products, such as high pressure pump, magnetic pump and so on. It not only meets the requirements of these machinery in high temperature, corrosion, oxidation, abrasion, but also plays a sealing role in the normal operation of the machinery.
