lt provides high-precision homemade bearing of ordinary materiaI, incIuding deep groove baII bearing and fuII compIement cyIindricaI roIIer bearings.The materiaI refers to high-quaIity bearing steeI, thermaI treatment technoIogy is put under strict controI,and it is abIe to carry out cryogenic treatment. And fuII compIement cyIindricaI roIIer bearings adopts advanced roIIer furnace for thermaI treatment. Other technoIogies are aII processed by fuII-automatic and semiautomatic equipment, and the production technoIogy and quaIity controI are arranged as per P5 precision. lt products wideIy support home and abroad manufacturers of eIectric tooIs, mechanicaI equipment, automobiIe components, etc.
