608zz 608z 608 Ceramic Ball Bearings ZrO2 Si3N4 SSiC

608 All Ceramic Ball Bearings In Material Of ZrO2 or Si3N4 or SSiC

Description of All Ceramic Ball Bearing 608 :

1. HIP-ZrO2 races and balls are made by highly purified, sub-micron and after Y2O3-TZP stabled zirconia powder material, are processed by AP (Atmospheric Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology, their properties are highly improved.

2. HIP-Si3N4 races and balls are made of highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, and is processed by GPS (Gas Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology. their properties are highly improved after HIP process.

3. SSiC races and balls are made of highly purified, sub-micron silicon carbide material. The atmospheric pressure solid phase sintering method at a high temperature of 2250°C are used to produce SSiC (Sintering SiC), can resist corrosion by hydrofluoric acid, which is the most excellent ceramic material with the best corrosion resistance among the known materials.

4. Cage and seals: The material of cage can be chosen among PEEK, and Nylon, the material of seals can be chosen among PEEK, , Rubbers and stainless steel. PEEK and material has similar corrosion resistance to ceramic materials, and has a good resistance to radiation, self-lubricating properties, a high degree of wear resistance and other characteristics, which are our recommended materials.

Why choose us:

Zhongxing Shiqiang Technology (Tianjin) Co., Ltd. mainly produces ceramic rolling bearings and ceramic balls. At present, the company has a production line for automatic grinding and assembly of ceramic bearings, and designs an annual output of 3 million sets of 608-2PS, 608-2TS, 608-2RS and 608-2Z all-ceramic bearings and mixed ceramic bearings whose precision grades can reach P5 and P4.

  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.
