Suzhou Jincheng Bearing Co., Ltd., was founded in 1992 as one of the first private needle roller bearing manufacturers to emerge from the then nascent market economy.
On the R&D front, since 2014, SJB has obtained 42 patents from CNIPA, 10 of which are invention patents. All of these, accompanied by the recent completion of a fourth heat-treatment production line, has enabled SJB to reach a manufacturing capacity of 80 million bearings a year.
