Silicon Carbide Mechanical Seals For Rotating Machinery

Description of Customized SSiC Mechanical Seals:

Mechanical seal is a kind of shaft sealing device rotating the michanery, it is formed by at least a pair of end face perpendicular to the rotation axis, and under the force of fluid pressure and compensation institution elastic force (stone force) and with the cooperation of the auxiliary seal, the faces keep seat and the relativ sliding, to prevent the fluid leakage.

The rotating ring and static ring is generally formed by the group of pure SSiC rings, or one SSiC and the othe is SSiC+C material.

Rotating and static ring: a pair of pure SSiC rings, applicable for strong corrosive medium.

Rotating and static ring: a SSiC ring, and a SiC+C, applicable for the medium easy to vaporized.

Performance advantages of SSiC (Pressureless sintered silicon carbide):

Why choose us:

Our pressureless sintered silicon carbide products has high density and high hardness, we can volume produce many kinds of and many shapes of complicated mechanical seals in material of SSiC.

The advantages of our company:

We have three factories in China, can meet the needs for different customers, and also we have advanced pressing, sintering and processing machines. Our company has specialized production of high-precision ceramic ball production line, as well as ceramic bearing grinder, automatic assembly production line. In addition, our HIP sintering furnace from Sweden ABB company, so we are confident that you will be satisfied with our products.

  Beijing Zhongxing Shiqiang Ceramic Bearing Co., Ltd., founded in 2005, situated in No. A38 Weishanzhuang Industry District, Daxing District ,Beijing, is the first company in China to invent and manufacture rare-earth ceramic bearings. The rare-earth ceramic bearings have characteristics of strong resistance against all kinds of acid, alkali, salt and other corrosive medium erosion, high temperature resistance, wear-resistant, dimensional stability at high temperature, etc. They can be used in worse lubrication working condition with a long operating life, thus it is a new kind of high-tech products material, with great social and economic value.

  Besides, the founder of the company started theoretical research and process development on ceramic bearings as early as 1982, and obtained two national invention patents in 1992/1994 (Patent No. ZL92114993X for rare-earth ceramic bearings and Patent No. ZL94106294.S for ceramic ball processing technology).

  At present, our company mainly produces ceramic bearings, sliding bearings, ceramic balls and ceramic industrial parts. The production materials are high performance ceramic materials, mainly SSIC, Si3N4, ZrO2, Al2O3.

  The advantage of our company is that we have specialized production line for high precision ceramic balls, and we can produce customized GPS (Gas Pressure Sintering) and HIP (Hot Temperature Isostatic Pressing) sintered Si3N4 balls and ZrO2 balls. The quality of our products is equivalent to ASTM F2094 F2094M-08 standard class I and II materials, and the precision grade reaches international standard G3, G5, G10 ceramic bearing balls, etc. Please note that the most of equipment used in our production and testing process are from Mitsutoyo Japan, and the hot isostatic sintering furnace is from ABB Sweden, therefore, the quality of our products is absolutely superior. And we are confident that you will be satisfied with our products.

  In 2017, Liaoning Zhongxing Shiqiang New Material Co.,Ltd., was founded, situated in 571 Jianshe Road, Jingkai District, Anshan City, Liaoning Province. The company mainly produces sliding bearings as well as pump accessories. And the pump accessories are mainly sold in domestic famous pump manufactures.

  In 2020, Zhongxing Shiqiang Technology (Tianjin) Co., Ltd., was founded, situated in No.41 Guangyuan Road, Wuqing District, Tianjin. The company mainly produces rolling bearings as well as ceramic balls, and its productions are competitive in the international market.
