12T 14T 16T Heavy Duty Germany Drum Type Axles for Semi Trailers

QC management system Implementing IATF 16949:2016

Services quality management system Implementing ISO 9001:2015

Product technical standard Implementing JT/T 475-2020

Fatigue life 1,700,000 cycles

Raw material for beams 20Mn2 seamless steel tube from China's top 3 steel mills

Axle beam Spinning forming

Intermediate frequency quenching

Tempering

Better load capacity service life

Beam machining Using a special Double-head CNC Lathe, both ends of the beam are processed at the same time, and the axle coaxiality is guaranteed;

 

Medium frequency quenching is used at the bearing mounting position to obtain strong fatigue resistance;

???????

The bearing mounting position is processed by Fine Grinding Process to meet the high dimensional accuracy requirements of the designed axle;

???????

The brake base plate welded on the axle is bored with a special Six Hole Boring Machine to ensure that the parallelism of the six holes meets the design requirements of the axle.

One-piece beams  Using high-quality low alloy steel and double-head extrusion process to obtain high loading capacity, long service life, light weight and remarkable performances.
