In 1982, the founder of Beijing Zhongxingshiqiang Ceramic Bearing Co., Ltd. (ZXSQ), Mr. Kui Jiu Wang, who started the research of rare-earth ceramic, with 10 years' hard work, spends all his and his relatives' money on ZXSQ. Finally in 1992 we were granted with the Chinese National Original Development patent (rare-earth ceramic bearing patent. Patent No. ZL92114993.X). Since then without the help from outsiders, Mr. Wang has led his three sons devoting themselves to ceramic bearing business. When nobody has the confidence to the product, the families have created a miracle in the ceramic bearing.
After 7 years' continuous improvement and renovation in 1999, the first factory of ZXSQ was set up in Harbin and is the pioneer of ceramic bearings in China. For more fast expansion and for better man power resources, ZXSQ moved to Beijing, the current location in 2003. Now our factory owns 6000sqm land with 4000sqm workshop and over 100 workers.
As all kinds of key production equipment including high temperature furnaces, special machines for bearings, grinding machines for ceramic balls are made in house, ZXSQ has the capability to produce the ceramic parts according to customers' specifications in a very short time to meet client's requirements.
As to the production technology with non-stop developing inspiration, we are capable to make balls with sizes from 0.5 to 90mm at the grades of G5-G100 made of different ceramic materials.
For full ceramic ball bearings, we are capable to make the maximum 200mm outer rings and the smallest 3mm inner rings for all kinds of ceramic materials with PEEK, PFA, Teflon, Nylon or Graphite reinforcing cages (retainers). Besides we are also producing hybrid ceramic ball bearings (outer rings and inner rings are made of steel together with ceramic balls). Our products have been exported to the USA, Germany, Japan and Korea.
Although ZXSQ is still a small unit in the ceramic bearing and part fields, ZXSQ is heading for the brighter future. We hope you will join us and let's face the world together
