Our co***ny, covering an area of 100,000 square meters, was founded in 1987 and incorporated in 2000 as a specialized manufacturer of all types of bearings. Having experienced continuous growth over the past 15 years, we now have fixed assets worth in excess of USD24,000,000 and employ 1,300 personnel. With more than 600 sets of imported and domestically produced equipment, we are outputting over 8,000,000 sets of bearings annually.
The main products we currently manufacture include high precision cylindrical roller bearings, deep groove ball bearings, angular contact ball bearings, spherical plain bearings, railway bearings and non-standard bearings. These series are mainly applied in automobiles, marine engines, electric motors, machine tools, and general machinery. With advanced technologies and management, we obtained ISO9002 and ISO14001 certificates in 1994 and 1996 respectively.
We have adopted internationally advanced processing technology. As the first domestic manufacturer to introduce German URW-160 BAD DUBEN vertical type bearing ring cold rolling forming machinery, we have also imported many sets of RIWA-2 and URWA-1x horizontal cold rolling forming units. By using these equipments we have been able to reduce consumption of raw materials by 20%, and improve the metallurgical structure of bearings; thereby prolonging their life ***ns threefold.
Other advanced equipments include four RGB and RCI series heat treatment production lines with a treatment quantity totaling 1.2MT per hour. Multi-points temperature control meters and CNC display meters with bi-directional control have been adopted to complement these units. Due to homogeneous furnace temperatures, processed parts have little deformation, with the color being silver-gray and free of decarburization after quenching. Products manufactured using these furnaces are better in quality than stipulated in the relevant national standard, with the bearing service life being substantially extended.
