XC differential shaft maintenance increases the durability of the transfer fitting by repeated rotation of the auxiliary steel, and increases the fixed bearing curve sliding easily-movable classification material for maintaining good vibration function at both ends.

  Point 2: Design principles to prevent distortion

  According to the welding process in the bearing, it can increase the maintenance of the technical process, the principle of large sliding, increase the engineering of electroplating molecular height, increase the bonding area to bear the advantages of more accurate shape method.
