Products DescriptionThe difference between American type trailer axle tube produced by DARO Group and German axle tube mainly lies in the axle head. The axle head and shaft body of American type trailer axle tube are shaped from a 20Mn2 seamless steel pipe. There is no need for manual welding in the middle, so the connection is more natural and load-bearing. In addition, the axle head has higher bit wall thickness and is more durable and resistant. Therefore, compared with German axle tube, American type trailer axle tube has better load-bearing capacity.ModelMax.
