        Quality inspection

        The product is controlled by quality improved rather than by simply quantity increased.Using the complete quality control system,we have strict inspection on process of manufacture, to assure each bearing to meet technical specification,and all products have full inspection including: width/OD/ID diameter precision measure, bearings’hardness tesing, bearings’ Round measure, Low noise testing. Control of grinding, Max speed. Bearing life.
