35#,45#,QT600,40Cr or 42CrMoE for connecting rod body ;
Aluminium-magnesium Alloy and Babbitt Alloy for upper bearing shell ;
ZCuSn10Pb1,Aluminium-magnesium Alloy or Babbitt Alloy for lower bearing shell , 40Cr,35CrMoAlA or 42CrMoE forging for connecting rod bolt .
Integral cast aluminum-magnesium alloy bearing bush with high strength, low friction coefficient and long life
At the point of forced lubrication, the pressure bearing capacity of the whole machine is 5 times that of the babbitt bearing bush, and the service life is more than 3 times, and its special material performance can provide reliable operation guarantee for the crankshaft.
