201712111103189794762.jpgIt is 30490N. It is much lower than SACHS. It has no enough pressure force on the disc, which results in the heating and damage of the facing.
  • Diaphragm

2-1.jpgThe material is 50CrVA, HRC 55-60 (Tip site), which ensures the high pressure force and guarantee 1.5 million working times, that means at least 6 years working life.
2-2.jpgThe material is 65Mn, no enough pressure force,after several months using, the pressure force will be declined, which results in slipping between the facing and pressure plate, and heating the facing, getting damaged.
  • Thickness of the cover

3-1.jpgIt is 7.3mm,same as SACHS and strong enough.
3-2.jpgIt is 5.5mm,not strong.
