All the axles are integrative axles:
    1、Axle body and axle head are integrated not by welding but by high temperature extrusion. The metal fiber of axle body is  streamline and not destroyed by manufacturing procedure. Therefore, it increases strength of axle body and makes appearance perfect.
    2、After axle body is heat treated, the grain size will reach level 7 to level 8 which is in the perfect condition.
    3、Compare with other same tonnage axles, this type axle is lighter in weight and higher in capacity. The dynamic load factor is over 2.5. Therefore, it is economical.
    4、These types of axles use non-asbestos brake lining, so it can protect the environment.
    5、These types of axles use the international standard spare parts, so it is convenient and economical.
