Taperd Roller Bearing SZY thin wall bearing recently developed to replace imported products bearing characteristics, and each of its series of cross-sectional size was designed to a fixed value, with a series of cross-sectional size is unchanged, it does not increase the diameter size increase for modern mechanical design of rotating bodies compact, lightweight and simplify requirements. It is a small size, light weight, low friction characteristics, widely used in aerospace, precision machine tools, industrial turntable, radar communications, industrial robots, semiconductor processing equipment, optical processing equipment, medical equipment, textile machinery, and other fields, These devices can significantly save space and reduce weight, reduce friction, and provide good rotation accuracy.
