1,The axle beam is made of good quality alloy steel(20Mn2), adopting whole piece heat treatment to increase the hardness and tension.Frequency-quenching treatment is adopted in the bearing position to increase the durability and anti-fatigue capability.

2,The brake assembly has a long life, without noise, and is friendly to the environment.

3,Mobil XHP222 grease can prolong the bearing's life and improve the energy efficiency.

4,The world well known brand bearings have great bearing capacity, high rotary speed, excellent rigidity, heat shock and vibration.

5,Hub bolt is made of alloy steel ,with high strength ,great tensile.
