In 1988, we have developed plastic cages cooperated with Shanghai Bearing Co., Ltd. for manufacture domestically of Santana and became a supplier to Shanghai Volkswagen. The products were awarded the eighth Jiangsu Provincial superior new product gold medal.

In 1989, we have developed all kinds of engineering plastic cages used for rolling bearings in technical collaboration with Luoyang Bearing Research Institute and became a supplier to HRB, ZWZ, LYC and etc. We have convened bearing factories to carry on technological exchange and popularized engineering plastic cages presided over by Luoyang Bearing Research Institute. The “Plastic Cages for Short Roller Bearings” were awarded the certification of national level new product in 1995, and the ninth Jiangsu Provincial superior new product gold medal.

In 1993, we drafted the Industry Norm JB/T 7048-1993《Rolling bearing engineering plastic cage specification》and JB/T 6638-1993《Glass fiber reinforced polyamide specification for rolling bearing cages》together with Luoyang Bearing Research Institute, and awarded the science and technology progress third prize of ministry of machinery industry in 1995. We participated in the revise of JB/T 7048-2002《Rolling bearing parts-plastic cage- specification》in 2002.

In 1998, ISO 9002:1994 Quality Management System has been widespread applied in our company and accredited by BVQI of France at the end of 1998; it has been also transformed into ISO 9002:2000 in 2001. ISO/TS 16949:2009 Quality Management System has been accredited by OQS of America in September 2009.

In 2006, we newly built workshop in the development zone for expansion of production and developed railway bearing plastic cages cooperated with Ministry of Railways, Dalian DZ Bearing Co., Ltd. and Wafangdian Bearing Group Corp. The new product has been passed the bench test and is being carried out on the road test at present.
