With over ten years' of development behind us, we specialize in manufacturing deep groove ball bearings and trading all other types of bearings. Our main products include deep groove ball bearings ,cylindrical roller bearings, spherical roller bearings, needle roller bearings, ball bearing units, water pump bearings, automobile bearings, linear motion bearings, oil-less bearings, bush and self-lubricating bearings, and non-standard bearings. To ensure that all bearings meet our stringent quality standards, we not only choose suppliers of materials very carefully, but have also set up our own in-house QC institute. Tested at each stage of the manufacturing process, random inspections are also conducted on every product lot before being shipped to customers. With our series being exported into numerous markets overseas, the "Superoll bearing world" now extends from Japan in the east to the USA in the west, and from Russia in the north to New Zealand in the south. In 1997, we constructed a new factory in Ningbo, Zhejiang Province, to exclusively produce high quality, low noise and long life deep groove ball bearings. Outputting 70,000,000 sets of these products annually, this facility is equipped with automatic manufacturing lines and precision testing machines. Employing a team of professional engineers, we are devoted to constant technical improvement. Moreover, in 2001 we were granted ISO9000 certification, thereby providing a further guarantee of product quality. If you are interested in any of our bearings, or have an OEM order to complete, please contact us with your correspondences. We look forward to having the opportunity of working together with your company for mutual success.
