SACHS 1878001152 OKA/BEWO Heavy Duty Truck Clutch Disc 380Mm For Sinotruck Man / BENZ Made In China

From material selection to factory inspection, the most complete international standards are adopted. And the products use OEM standard materials. Especially the core component of the disk hub is made of 40Cr and undergoes quenching and tempering to make Rockwell hardness reach HRC28-32. The steel sheet is made of 65Mn and has been quenched to make the Rockwell hardness reach HRC38-42. So it is not easy to deform. With the use of SPHC carbonitriding, the damping disc is ductile enough to withstand large tonnage stamping while also achieving Vickers hardness HV600-700 The spring is made of 55CrSIA material, which ensures that it does not break and the shorting amount is less than 0.5mm after working for more than 3 million times The face sheet is made of asbestos-free material, which has the characteristics of high temperature resistance, and the friction coefficient is 0.27-0.40. It can guarantee a service life of at least one year.
