Various of shafts made of alloy steel, carbon steel, stainless
steel that mainly used for transmission, mining equipment and so on
have good mechanical properties. Drive shaft is composed by axel
tube, flexible sleeve and cardan to joint or assemble the fitting
parts, makes the items movable or rotation. Its usually made of
light alloy steel tube that have good enduring twist.
